March 2007 -- Some Finishing Touches Under the Hood

A couple more photos of the finished engine and engine compartment. The only thing left on the to-do list here is to re-paint the air cleaner and apply some reproduction decals for the jack mounting instructions and engine emissions information. Finding reproductions for the emissions decals which were originally located on the air cleaner housing is proving to be rather difficult though. So far, I've only been able to find similar decals listed for a 78 454. These are the original decals for the 400:

May 2007 -- A Factory Tachometer Cluster & Some Interior Work

After a bit of searching, I found an instrument cluster with the factory tachometer option (RPO U16) to swap into Dad's 77. There were numerous different versions of these clusters used over the years. I'm working on putting together an identification guide for them. This particular cluster was chosen because it has a voltmeter and a mechanical oil pressure gauge, making it a direct plug-in swap for this truck which was already equipped with a similar RPO Z53 gauge cluster.

Swapping one of these factory gauge clusters (with or without the tachometer option) into a truck that was originally equipped with warning lights is a bit more involved. I'm working on a swap guide for that procedure.

The original interior is still in decent condition but some areas still need a little work. Still on the interior to-do list is:

I used some SEM Color-Coat to recolor the faded door and kick panels. They didn't list this truck's interior color code (GM #25) in their color library but their technical support staff was very helpful. I mailed them a color sample and received a mixing formula within a week. The formula they provided for this color is:

SEM COLOR NO. COLOR NAME USED IN MIXING CUMULATIVE GRAMS PER PINT CUMULATIVE GRAMS PER QUART
1554 TINTING WHITE 44.4 188.5 377.0
1553 FAST BLUE 28.5 309.5 619.0
1559 YELLOW OXIDE 20.3 395.7 791.4
1501 LANDAU BLACK 10.7 441.1 882.2
TOTAL 103.9

June - July 2007 -- Finishing up the Exterior Trim

Most of the original trim that divided the two tone paint was in poor condition and was discarded when the truck was painted back in 1989. For 1977 only, GM used "ochre" (yellow) accent stripes on the trim instead of black. I think it may have been an anniversary year for GM trucks or something. Anyway, Dad purchased many new pieces of trim from the local GM parts dealership years ago but had to get most of the pieces with the more common black stripes (used from 1973-76 & 78-80). I used some lacquer thinner to remove the black paint, spent a lot of time masking off the trim, and re-painted them with Nason Ful-Thane urethane in Bahama Yellow which is a very close match to the original ochre yellow.

The paint job I sprayed on the truck last summer had a little bit of orange peel texture that I wasn't happy with. So I decided to do some sanding and buffing before installing the new trim and emblems. I wet sanded with 1500 grit followed by 2000 grit to remove the orange peel and dust nibs. Then I buffed the paint with Meguiar's #1 Medium Cut Cleaner followed by their #9 Swirl Remover to restore the shine. This was my first time sanding/buffing a paint job and I've since learned that the products I used are somewhat old technology compared to the newer products Meguiar's has to offer. Still, they seemed to do a good job in my opinion.

July - August 2008 -- Re-Painting the Wheels and New Tires

We took the old 235/75R15 Bandag retreaded GoodYear tires off the truck and replaced them with a set of 31x10.50R15 Dayton Timberline A/T tires. The old Bandags were great snow plow tires but very noisy on the road. While the tires were off, I took the opportunity to sandblast the wheels and spray them with some epoxy primer followed by some Nason Ful-Thane urethane in the original shade of white. Although not original to this truck, these 15"x8" wheels are factory GM RPO-PA6 wheels. They can be distinguished from similar looking aftermarket wheels by the rounded/rolled edges of the triangular openings and the threaded center cap mounting holes.

November 2011 -- New Upholstery for the Seat and Headliner

After storing the truck for the winter, we removed the seat and headliner and took them to the upholstery shop for repair. The headliner will be getting re-covered with some original type perforated vinyl. The seat will also be getting re-covered with original type vinyl on the sides and cloth on the seating area. Hopefully the upholstery shop can find a source for some of the original cloth. It's a ribbed pattern velour that (from what I've found) was only used in GM trucks for 2 or 3 years in the mid 70's.

Summer 2012 -- No New Upholstery Yet

After months of searching, the upholstery shop was unable to find a match for the original seat cloth. The closest they found was from SMS Auto Fabrics. It was an exact match on the pattern but the color was way off (and kind of green looking) as compared to an un-faded section of the original where the back/bottom overlap.

So we made the decision to to give up on trying to find an exact match and just go with some velour that we picked out of one of the upholstery shop's sample books. We found some that looks very similar to what GM used in the 78/79 trucks. In the meantime, we put the old aftermarket seat cover on a seat we pulled out of a parts truck and stuck that in there for the summer.

January 2013 -- The Seat is Finished

The seat is back from the upholstery shop and looks great even though the cloth isn't the exact original style. We also got a new carpet made by Auto Custom Carpets, Inc. that will be going in along with the seat. Their blue #802 cut pile carpet is a nearly perfect match to the original and matches the original lower door panel carpet a lot better than the darker blue carpet currently in the truck.

July 2013 -- Interior Update

We finally got around to installing the new carpet and re-upholstered seat. I freshened up the faded plastic on the seat hinge covers and the seatbelt retractor covers with SEM Color Coat.

Still on the to-do list is replacing the headliner and spraying the headliner trim pieces and faded dash pad with SEM Color Coat. That will pretty much finish up the interior restoration work.
