    Parting 85 GMC

    Hi Everyone! It's time for it to go - 1985 GMC, originally had a V-6/TH-400 but now has a locked-up 350 from the 70s in front of the TH-400. A race shop I work for wants the bed/chassis for a trailer, but the front suspension and cab/interior bits are available. Manual windows/door locks...

    Eastwood Versus POR15

    Hi Everyone! FINALLY starting the first stage of reassembly, painting the frame. I'm tired of not finding someone to blast the frame, so I'm going to do it myself in the driveway. Once I get it "clean" (no old flaking paint, it's not very rusty so I'm looking for a good surface for the...

    Interior Color To Compliment Exterior Color

    Hi Everyone! Been trying to get work done on Project Calvin but health/work/other projects (house renovation) have taken just about all of my time. As I collect parts and prepare for future purchases I wanted to ask opinions on what would be the best choice for a complimentary interior color...

    Front Crossmember Degreasing

    Hi Everyone! Now that I finally have things in place to get back to the 85 GMC rebuild I want to make sure the 2WD front crossmember is clean inside and out. I previously pressure-washed it with a ton of Purple Power degreaser, but I'm just not 100% sure it's clean on the inside. Keep in mind...

    Trailer Wiring Adapter

    Hi Everyone! As I'm upgrading the 78 C20 and working towards the wiring on the 85 GMC I was wondering if anyone has any experience with a plug-in trailer wiring adapter for a flat 4-pin trailer plug? This would be separate from the car trailer wiring, I have a pickup bed trailer that doesn't...

    Barn-To-Garage Renovation!

    Hi Everyone! This project has seemed to take FOREVER, but finally I'm seeing true progress! The house I'm renovating was built somewhere between 1905 and 1909, and it's my belief that the "barn" is at least that old. Originally there was a wooden building just to the east of this building...

    TH-400 Engagement Delay?

    Hi everyone! In my ongoing saga of the 78 2WD 3/4-ton "Blackie" I recently replaced the fluid and filter, plus replaced the pan with an aftermarket pan with a drain plug. After replacing the fluid it seemed to take a lot more than normal (per CSM) to get the trans dipstick to read "full" -- I...

    Glasstite Topper Replacement parts

    Hi Everyone! While I'm making plans to replace the rear springs on my 78 3/4-ton (another thread) I wanted to spend a little time looking for replacement parts for the topper I will have on my 85 GMC: It's a Glasstite cab-height (with a little extra) topper, and I need to find replacement...

    3/4-Ton 2wd Rear Spring Replacement: Advice?

    Hi Everyone! In order to get Project Calvin back on track I need to replace the rear springs on my 78 3/4-ton -- one has the main leaf broken just aft of the U-bolts. I have everything on-hand to replace (including shocks while I'm at it), the only part I have to re-use is the plate the...

    Upper A-Arm Mounts: Replace Studs or Replace Bracket?

    Hi Everyone! Been a while since I last checked in, have been too busy with the full-time job to devote much time to the truck. However, I was able to get some "wrench therapy" in today, and finished removing the front suspension. Hopefully tomorrow I'll be able to remove the front crossmember...

    Scrapping Truck -- Parts To Keep?

    Hi Everyone! Finally got the 1985 GMC parts truck over to the house to start dismantling it -- a friend of mine is going to use the bed/chassis for a trailer (cab is toast, way too much rust). While I don't want to save every nut and bolt (don't have _that_ much room) I do want to save parts...

    CB Radio Antenna Recommendations?

    Hi Everybody! I have an original Delco AM/FM/Cassette/CB Radio that I want to install in my 85 GMC and am curious as to what others have used for the CB antenna. I would prefer something less obtrusive than the whip antennas from days gone by. Thanks in advance for helping me out!

    New Again -- Bought Another Square Body!

    Hi Everyone! While the progress on my 85 GMC 1/2-ton is moving slowly, I needed a truck NOW. So I found one: 1978 Chevy 3/4-ton for a whopping $3,000.00 -- so far it's money well spent. It has issues, but nothing like the turd of a 1970 C/10 it's replacing. Decent list of options: dual tanks...

    TH-400 w/Carrier Bearing?

    Hi Everyone! Went over to look at parts on the second 85 GMC I have (parts truck), crawled under the side and see that it has a TH-400 with a 2-piece driveshaft. Because this truck initially had a Vortec V-6 in it I'm now guessing that both the engine and transmission have been replaced in it...

    1985 GMC Truck Project

    Hi Everyone! I'm working on taking two 1985 GMCs and building one good one, with an Olds 350 and TH-400 transmission. It'll not be stock, but nothing too radical -- this will be used to haul my race car trailer and see a lot of time on the streets. Look forward to asking a bunch of questions...
