General Interchange Information

Most of the information in this section will eventually be incorporated into the year-specific listings in the above links. But I will still leave it here for easy reference.

Body Style Differences (2 door / 4 door / hardtop / sedan / station wagon / convertible)

Both 2 and 4 door cars are the same from the firewall forward. Floor pans, trunk floors, and trunk lids are also interchangeable between 2 and 4 door cars. Dashboards, instrument panels, and steering columns are also the same. Front seats will also interchange, but 4 door seats do not fold ahead for access to the back seat.

All '68 - '79 2 and 4 door glass is entirely different between the two body styles. Most '62 - '67 glass is different as well, but windshields are common for 2 and 4 door sedans as well as wagons.

A hatchback was available from '73 - '79. These share many parts with 2 doors of the same year range ('73 & '74 vs. '75 - '79). The differences are in the rear window, rear seat, and rear interior pieces.

From '62 - '67, both coupe and sedan models were available. Sedans have a stationary frame around the side window openings. They are often called "post cars" due to the post that remains between the front/rear windows when they are both rolled down. Many parts will interchange between sedans and hardtops. The exceptions include the glass, associated trim, doors, and roof.

The '62 - '67 Chevy II/Nova was also available in a station wagon. Everything from the firewall forward is the same as all other body styles of the same year. Front doors are interchangeable with 4-door sedans. Rear doors are also interchangeable with 4-door sedans but require the wagon window frame to be transferred over to the replacement door. All other roof, rear window, and tailgate parts are pretty much unique to the station wagon body style.

Convertibles were available in '62 and '63. Many parts (such as the doors) are interchangeable with '62 - '65 2 door hardtops.

Interior Parts

1962 - 1965

I do not have any detailed interior parts interchange information for these years yet.

1966 - 1967

I do not have any detailed interior parts interchange information for these years yet.

1968

In general, many '68 interior parts are unique to this year. This was the first year for the new body style but the last year for the dash mounted ignition switch. That made for a unique steering column, dash, and instrument panel. The A-pillar trim pieces are also unique to '68 due to the way the bottoms are shaped to meet the dash.

Interior door lock knobs were moved farther forward in '69 so the '68 doors and interior door panels are specific to '68. Seats are unique to '68 as well since head restraints were optional this year. The ash tray and brake/clutch pedals are some more '68-only parts.

1969 - 1972

Nearly all '69 to '72 interior parts are physically interchangeable. However, door panel and seat upholstery patterns/styles changed from year to year. 1969 featured padded A-pillar trim while '70 - '72 are metal. High back bucket seats were introduced in '72.

Instrument panel outer bezels are all interchangeable from '69 - '72. The '72 bezel is slightly different since it has a "Fasten Seat Belt" light. Later year ('73 - '76) bezels will fit a '69 - '72 but they have a different pattern ("grained" instead of "ribbed" and they do not use a cover panel under the steering column. Use of a corresponding year under-dash steering column hanger bracket may be necessary to properly align the height of the column with a '73 - '76 bezel.

1969 - 1970 instrument panels have pale green colored numbers while the otherwise similar looking '71 - '74 instrument panels have white numbers. Cars equipped with the optional RPO-U17 "special instrumentation" package feature a tachometer in the left hand opening normally occupied by the gas gauge. The gas gauge on these cars is moved to a gauge pod at the front of the console (which also includes an oil gauge, temperature gauge, and ammeter).

Non-AC heater controls are interchangeable from '69 to '76. The '69 & '70 controls have pale green lettering while '71 - '76 have white lettering. Also, the defroster setting on '69 & '70 controls is labeled "DE ICE" as opposed to "DEF" on the '71 - '76 controls. AC controls are likely interchangeable from '69 to '76 as well.

Steering columns are interchangeable from '69 - '74. A tilt column option became available in '73. The '73 - '74 tilt column is a direct bolt-in swap into a '69 - '72. A later '75 - '79 Nova column can also be used with some minor modifications. See the "Miscellaneous" section below for details.

1973 - 1974

Most '73 - '74 interior parts are interchangeable between the two years. The seat belts, headliner, and headliner trim are different due to the retractable shoulder belts introduced in '74. 1974 Novas were equipped with a seatbelt-starter interlock system that used weight sensors in the front seat(s). This interlock system can be easily disabled so swapping in different seats without the sensors is not a problem.

'73 and '74 instrument panel outer bezels are identical. Many '75 and '76 Novas also use a very similar looking (but slightly different) outer bezel with a different style instrument cluster mounted in it. Some models (such as the '75 LN and '76 Concours) used special color-coordinated and/or woodgrain instrument panel bezels These would still physically interchange with a '73 - '74 bezel though. The earlier year ('69 - '72) bezels will fit a '73 - '76 but they have a different pattern ("ribbed" instead of "grained") and they use a cover panel under the steering column. Use of a corresponding year under-dash steering column hanger bracket may also be necessary to properly align the height of the column with a '69 - '72 bezel.

'73 and '74 use the same instrument panel as '71 - '72. A '69 - '70 instrument panel will interchange but it has pale green colored numbers instead of white. Cars equipped with the optional RPO-U17 special instrumentation package feature a tachometer in the left hand opening normally occupied by the gas gauge. The gas gauge on these cars is moved to a gauge pod at the front of the console (which also includes an oil gauge, temperature gauge, and ammeter). The optional console used in '73 - '74 Novas is similar to the '68 - '72 console except for the area around the shifter which bumps out towards the driver seat.

The '73 - '74 dash pad is nearly the same the '69 - '72 pad but the grain texture is slightly different.

Non-AC heater controls are interchangeable from '69 to '76. The '69 & '70 controls have pale green lettering while '71 - '76 have white lettering. Also, the defroster setting on '69 & '70 controls is labeled "DE ICE" as opposed to "DEF" on the '71 - '76 controls. AC controls are likely interchangeable from '69 to '76 as well.

Steering columns are interchangeable from '69 - '74. A tilt column became an option starting in '73. A later '75 - '79 Nova column can be swapped into a '74 or earlier Nova with minor modifications. See the "Miscellaneous" section below for details.

The hatchback body style was introduced in '73. It shares many interior parts with 2-door cars but the rear seat and rear interior panels are unique to the hatchback body style.

1975 - 1979

For the most part, '75 - '79 interior parts are interchangeable. The dash (re-designed for 1977) is the most significant exception.

The "regular" '75 - '76 Nova instrument panel outer bezel is very similar looking to the '73 - '74 outer bezel but the "grained" areas below the speedometer and around the radio and light switches are slightly different size. The bezels are physically interchangeable from '73 through to '76 though. 1975 LN and '76 Concours Novas used special color coordinated and/or woodgrained bezels that are otherwise physically interchangeable with the "regular" bezels.

The instrument panel (speedometer and gas gauge assembly) is unique to '75 - '76 but it is physically interchangeable with the '69 - '74 instrument panels. As with the earlier years, the RPO-U17 special instrumentation package locates a tachometer in place of the gas gauge for '75 - '76 and re-locates the gas gauge to a gauge pod on the console. The '75 gauge pod is identical to the earlier years. The '76 gauge pod is very similar but uses a voltmeter instead of an ammeter. The '75 - '76 console is different than the earlier years.

The '75 - '76 dash pad is unique to those years but appears to be physically interchangeable with a '69 - '74 pad. This is due to the fact that the metal dash under-structure remained unchanged as did the shape of the instrument panel bezel where it meets up with the dash pad.

Both the dash pad and instrument panel were changed in 1977. Because of this, the '77 - '79 dash pads, instrument panels, and instrument panel bezels are not interchangeable with earlier years. The metal dash under-structure remained unchanged so it may be possible to swap all of the parts as a group. The electrical connector on the back of the instrument panel was also changed so a wiring harness swap would also be required. The new '77 - '79 instrument panel design has 4 round gauge openings. This allowed all optional gauge packages to be located in the instrument panel. A console gauge pod was no longer necessary.

Non-AC heater controls are interchangeable from '69 to '76. The '69 & '70 controls have pale green lettering while '71 - '76 have white lettering. Also, the defroster setting on '69 & '70 controls is labeled "DE ICE" as opposed to "DEF" on the '71 - '76 controls. AC controls are likely interchangeable from '69 to '76 as well. 1977 through '79 use a different style of control that is not interchangeable with '69 to '76.

Steering columns are the same from '75 to '79 but the wiring connector for the turn signal switch was changed in '77. Steering wheels were changed in '78 (style only -- they're still physically interchangeable). Seat belts were also changed in '78 (single roof mounted retractor).

The hatchback body style was still available from '75 - '79. Again, they shared many interior parts with 2-door cars except for the rear seat and rear interior panels. An optional Cabriolet vinyl roof was available on '75 - '79 2-door Novas which used unique interior panels around the rear side windows.

Miscellaneous Interior Parts

A '75 - '79 Nova/X-body steering column (including tilt columns) can be swapped into a '69 - '74 with some minor modifications. The '69 - '74 steering columns have a flange attached directly to the lower end of the steering shaft. A flexible "rag joint" coupler joins the steering box to that flange. The '75 - '79 steering column has a splined lower end which connects to an intermediate shaft via a U-joint coupler. The lower end of the intermediate shaft has the flange that attaches to the "rag joint" coupler on the steering box. A '75 - '79 column could be installed in a '69 - '74 using the following guidelines:

A windshield wiper delay control was available as an option (RPO-CD4) starting in 1975. Due to the similar instrument panel bezels, the '75 - '76 wiper delay system can be easily retrofitted into a '72 - '74 Nova. The wiper switch plug is slightly different on '69 - '71 Novas so additional modifications would be necessary for those years.

The wiper delay system consists of a special wiper switch and a control module that mounts under the dash. It simply plugs into the existing wiring and uses the existing wiper motor. A similar system was used on '77 - '79 Novas but uses a different switch due to the dash re-design and therefore is not suitable for retrofit into earlier years.

The rear door pull straps and chrome end caps on '75 - '79 4-door cars are interchangeable with the ones on '73 - '74 2-doors.

The chrome interior door release handles used in '75 - '79 Novas are the same as those used in many other GM cars including:

Mechanical Parts

Engines

Engines in early ('62 - '67) Chevy II/Novas used special front sump oil pans to clear the steering linkage. Small block V8 engines (283s and 327s) used in these cars also had recessed oil filters and a special location for the bellcrank pivot on manual transmission cars. The front sump oil pans, pivot relocation adapters, and other '62 - '67 V8 conversion parts are available through most restoration parts suppliers.

See my engine swap page for the details involved with an engine swap in a '68 - '79 Nova.

Most early/mid 60's small blocks use heads without accessory holes. These engines also use short water pumps and often mount the alternator on the driver side. Power steering pumps (if equipped) are mounted below the alternator and air conditioning compressors (if equipped) are mounted on the passenger side of the engine. Since there are no accessory holes in the heads, the lower alternator mount is usually bolted to (or cast into) the exhaust manifold. The upper alternator mount attaches to either a stud in place of the top left water pump bolt or to a mounting point on the front of the intake manifold. The power steering pump mount attaches to the front of the block (where 50's front engine mounts used to go) and wraps around to one of the side engine mount bolts. The lower A/C compressor mount attaches to studs that take the place of a couple exhaust manifold bolts. The upper A/C compressor mount attaches to a bracket bolted to the intake (w/longer bolts).

All 70's small blocks originally used heads with accessory holes. This results in an entirely different accessory mounting scheme than on the early/mid 60's engines. Now alternators are on the passenger side and air conditioning compressors (if equipped) are on the driver side. Power steering pumps (if equipped) stayed on the driver side but received new mounts. These engines also use long water pumps. For the most part, 70's and 80's small block (and some V6) accessory mounts are interchangeable. However, there were slight changes that took place over the years so it's best to get a complete set of compatible mounts from a donor engine when performing an engine swap.

'79 and earlier small blocks had the oil dip stick on the LH (driver) side. It was moved to the passenger side in '80. Some GM crate engines have provisions for an oil dip stick on either side of the block.

Timing tabs and harmonic dampers were also changed a few times over the years. Early small block dampers have the timing mark directly inline with the crankshaft keyway. It was moved about 10 degrees sometime around 1968. Another change occurred sometime around '76 or '77 with some of these engines having the timing tab moved to the top (12 O'Clock) position and viewable by looking down behind the water pump.

'74 & earlier power steering pumps used a keyed pulley retained with a nut. '75 & later power steering pumps used a slightly larger shaft with a press-fit pulley. The pressure line outlet fittings changed from an SAE inverted flare to a metric O-ring sometime around 1980. But the outlet fittings can be easily swapped from one pump to another.

Starting in '75, inline 6 engines began using an integral head and intake assembly. These can be swapped for a '74 or earlier head for use with aftermarket intakes.

Engine Compartment Items

All '62-'70 Chevy II/Novas use a windshield washer fluid tank that fits into a metal mounting bracket. '71-'74 Novas use a similar looking tank that attaches to the inner edge of the driver side fender with two screws. '75-'79 Novas also have the washer tank secured to the inner edge of the driver side fender but these years use a different tank that incorporates an electric washer pump.

All '68-'79 Novas use the same style rectangular body windshield wiper motor. '68-'74 have a mechanical washer pump mounted to the wiper motor. '75-'79 have an electric washer pump mounted at the bottom of the washer fluid tank.

Most Novas with 6-cyl engines did not originally use a fan shroud. Instead, they simply have a rounded guard built into the top radiator mounting plate. Fan shrouds were used on all Novas with V8 engines as well as later 70's Novas with 6-cyl engines and air conditioning.

Coolant recovery tanks were added sometime around '73 and three different designs were used over the years. The '73/'74 style tank mounts to the inner edge of the front fender up on top of the inner wheel well. I believe these tanks were usually located on the passenger side fender except on cars with A/C (which had the tank on the driver side). The second design tank was used only for '75. The '75 tanks were mounted on the passenger side fender with L6 engines and on the driver side fender with V8 engines. The third design tank was used from '76 to '79. It tucks inside the passenger side fender (next to the battery) and can easily be retrofitted to earlier year Novas (back to '68).

Air intake snorkel ducts were first used in '75. All '75-'79 6-cyl engines had a plastic duct/tube connecting the air cleaner snorkel to the oval shaped hole in the inner edge of the driver side fender. '75 V8's had a similar setup with a flexible duct hose connecting to the oval shaped hole in the inner edge of the passenger side fender. '76-'79 V8's had a plastic duct/tube with it's open end fastened to the top radiator support plate.

Transmissions

Both 3 and 4 speed manual transmissions were available in Novas. Two speed (PowerGlide) and 3 speed (TurboHydramatic) automatic transmissions were also available. This makes manual to automatic or automatic to manual transmission swaps fairly straightforward. The easiest way is to locate a donor car with the appropriate type of transmission. Many conversion parts can be purchased from restoration parts suppliers but some parts have been discontinued.

All Chevy engines (62-up inline 6, small and big block V8) use the same bellhousing bolt pattern which helps simplify engine/transmission swaps. However, not all transmissions are suitable for use behind all engines. For example, the TH200 transmissions used in some '76 and '77 Novas didn't even hold up well behind the 305s that GM used them with.

Two different size flywheels (manual trans) or flexplates (auto trans) were commonly used depending on the engine/trans combo. The larger 168 tooth one measures approximately 14" in diameter while the smaller 153 tooth one measures approximately 12-¾" in diameter. Many engine/trans combos will accept either size so long as the appropriate starter is used. See my Chevy Starter Info Page for more details on the various starters that GM originally used in the 60's and 70's.

Front Subframe / Suspension / Steering

1962 - 1965 share a common front subframe and suspension design. Due to improvements/changes, many '62 front end parts are somewhat unique to that year.

1966 - 1967 have a subframe and suspension design that is similar to '62 - '65. The major difference between the '62 - '65 and '66 - '67 subframes is the inner fender attachment points (bolts are horizontal for '62 - '65 and vertical for '66 - '67). '67 was also the first year for a dual chamber master cylinder and collapsible steering column. These changes made for different brake lines and a different steering box.

1968 - 1974 Novas share a common front subframe and suspension design. The '74 subframes have different front bumper mounting holes than the '68 - '73 subframes. The steering linkage is located behind the spindles so this design is often called "rear steer".

1975 - 1979 Novas share common front subframes and front suspensions. The steering linkage is located in front of the spindles so this design is often called "front steer". '79 Novas used spindles/rotors with larger outer wheel bearings.

The power steering boxes used from '68 - '79 are Saginaw 800 series boxes. They are interchangeable from '68 - '74. I believe that a '75 - '79 box will also work as long as a '68 - '74 pitman arm is used to account for the front/rear steer differences. '68 - '74 boxes have 4 mounting points but one is unused. The unused mount was eliminated on later boxes (starting sometime around '75). Later, metric fittings were used which will require either the matching lines and pump outlet fitting or adapters. There was also a change to the size of the input shaft sometime in the mid/late 70's so a corresponding year "rag joint" coupler may also be needed when making a steering box swap.

Manual steering boxes are also interchangeable in the '68 - '74 and '75 - '79 year ranges. A swap across those two year ranges is possible if the correct pitman arm is used to account for front/rear steer differences.

Front subframe mounting bushings are the same for '68 - '74 Novas (and other X-bodies) and '67 - '69 Camaros/Firebirds.

See below for more interchangeable Camaro/Firebird front subframe and suspension parts.

Rear Axles

1962 and 1963 ChevyII/Novas used rearends with a removable center section (similar to '55-'64 Chevy full size car rearends). These years used 4-lug wheels.

1964 - 1967 ChevyII/Novas used either an 8.2" 10-bolt or an 8.875" 12-bolt rearend depending on the original engine. The vast majority of '64 - '67 ChevyII/Novas were equipped with the 10-bolt. Only a few cars (those equipped with high performance 327's) received the 12-bolt rearends. Most (if not all) '64 - '67's have 5-lug wheels. The overall width and spring perch location is the same so a complete '64 - '67 rearend assembly can be swapped into a '62 - '63 in order to upgrade from 4 to 5 lug.

1968 - 1971 Novas were also equipped with either an 8.2" 10-bolt or an 8.875" 12-bolt rearend. Again, the 10-bolts are most common with the 12-bolts being used in cars equipped with big block V8's and high performance small block V8's. Due to the new body/chassis style, these rearends are wider than the ones used in '62 - '67 ChevyII/Novas.

Most 1972, and all 1973 - 1975 Novas were equipped with the GM "corporate" 8.5" 10-bolt rearends. These were used with all engine sizes and are nearly as strong as a 12-bolt. The overall width and spring perch location remained unchanged so these rearends are a bolt-in swap into '68 - '71's.

1976 - 1979 Novas were equipped with either an 8.5" 10-bolt or the weaker 7.5" 10-bolt. All '76 - '79 V8 Novas (except the '76 305) used the 8.5" rearend. The 76 305 and nearly all 76-79 6-cyl Novas used the 7.5" rearend. The 8.5" rear was an available option behind the 6-cyl engines for some years. Again, the overall width and spring perch location remained unchanged so '76 - '79 rearends are a bolt-in swap into 68-75's and vice versa. There is both a driveshaft length difference and an axle tube diameter difference when switching from a 7.5" 10-bolt to any of the other three (8.2", 8.875", or 8.5") rearends. The driveshafts used with the 7.5" rearends are about 1" longer. And the 7.5" rearend has smaller diameter axle tubes that use different U-bolts and lower spring/shock mounting plates.

See below for interchangeable Camaro/Firebird rear axles.

Brakes

Front disc brakes became an option in 1967. See Pat's Nova Disc Brake Swap Page for '62 - '67 Chevy II/Nova disc brake swap details.

Front discs remained optional on 1968 - 1974 Novas (they were standard equipment on the Nova SS from '69 - '72 though). All '68 - '74 disc brake assemblies are physically interchangeable but '68 discs used special 4-piston calipers and two piece rotors that are difficult/expensive to find repair/replacement parts for. They also use a unique spindle. So '68 style disc brakes are not really the best choice for most conversions. See my Disc Brake Swap Notes and LeadFoot's Nova Disc Brake Swap Page for details on the '68 - '74 Nova disc brake swap.

1967 - 1969 Camaro/Firebird disc brakes will also fit '68 - '74 Novas but again, the '67 and '68 discs used the more expensive 4-piston calipers and 2-piece rotors. Other pre '75 X-bodies ('71 - '74 Ventura, '73/4 Omega, and '73/4 Apollo) are also suitable disc brake donor cars for '68 - '74 Novas.

1967 - 1970 disc brakes used a separate distribution block/switch and metering valve. The distribution block/switch is the same as what is used with '67 - '74 drum brakes. 1971 - '79 disc brakes used a combination valve that included a metering valve, proportioning valve, and differential pressure switch all in one housing.

Front disc brakes became standard equipment on all Novas in 1975. The front suspension/subframe was also re-designed in 1975 so '75 - '79 disc brakes will not fit earlier Novas. Power brakes were still optional on '75 - '79 Novas but they were a required option when a V8 engine was ordered. 1975 - '79 power brake boosters are interchangeable.

Other X-bodies (Omega, Ventura/Phoenix, and Apollo/Skylark)

Novas share a fair amount of common body panels with their X-body cousins of similar years.

Similar models/years include:

Common parts include:

The different parts include:

** Interior parts are generally physically interchangeable between Novas and same/similar year X-bodies. However, there are some upholstery pattern and emblem differences on some parts. The '78 - '79 Pontiac Phoenix dash and instrument panel is an exception. They used a unique instrument panel and what appears to be a '75 - '76 Nova style dash pad. The '77 - '79 Buick Skylarks and Olds Omegas appear to use the same basic style instrument panels and dash pads as '77 - '79 Novas.

*** These vent panels are located on the B-pillars of '75 - '79 2-doors and Hatchbacks and serve as functional air outlets. Most have vertical ribbed louvers although some (mostly Pontiac I think) have horizontal louvers. '75 - '79 4-doors have decorative vent panels on the C-pillars (the functional ones are in the rear door jambs).

Camaros and Firebirds

1967 - 1969 Camaros and Firebirds share a few parts in common with 1968 - 1974 Novas. The front subframe and suspension components are interchangeable. Lower windshield molding, wiper motors, and wiper transmissions, and wiper arms are also interchangeable. 1969 Camaro steering columns are interchangeable with 1969 to 1974 Nova columns. Much of the firewall, cowl, and dash structure appears to be common between '67 - '69 Camaros and '68 - '74 Novas as well.

1967 - 1969 Camaro rearends are interchangeable with 1968 - 1979 Nova rearends but most Camaros in this year range were equipped with an 8.2" 10-bolt (some had 12-bolts).

1974 - 1981 Camaros and Firebirds share some parts with 1975 - 1979 Novas. The front subframes themselves are different due to the mounts for the body, bumper, and radiator support being different. However, the front suspension and steering components are interchangeable. Note that '70 - '73 Camaro/Firebird are similar but have some differences (different A-arms, bushings, etc). Also note that the outer front wheel bearing size was increased in 1979 so '79 - '81 spindles require the use of corresponding '79 - '81 brake rotors.
