1975 K-10 Project
« on: January 24, 2015, 03:31:30 pm »
I bought a short bed 1975 K-10 yesterday and thought I would introduce myself and share my restoration process here.

The truck is mostly unmolested, complete, has little rust, but needs a lot of mechanical attention.
My plan is to make it safe and reliable and hopefully stick with it until it is done.
Encouragement to finish will always be welcome.

Here is a picture from the seller. I'll take a few more once I have it home on Monday.

Welcome from Northern Illinois. That is a very nice looking short bed. What mechanical attention does it need?

Thanks for the comments.
I can't wait to get it home and start wrenching.
It has a lot of potential.

It needs:
Radiator
Engine refresh
Power steering gear (I am doing the pump and lines while I’m at it)
Tie rod ends
Brake system from the peddle back
Clutch (maybe just an adjustment)
Transmission shift linkage sloppy
Transmission tail seal
Transfer case seals at least
Fuel lines (need to inspect tanks and senders)
All suspension, cab, and bed bushings

I’m sure I’ll find more once I get it home.

Score.

Thanks
I think I did okay at $2750
This is exactly the truck I was looking for.

I was being generous at 10 feet. It looks much better 20+

I finally got the truck home after many hours at the DMV with the seller. Long boring story.

I put it on my lift and gave the old gal a thorough inspection turns out it may not be as bad as I first thought.
The first thing I did was to adjust the clutch linkage and to my surprise it now disengages and engages at about 1/2 peddle travel rather than at the very end. I am pleased.
Tomorrow I attack the sloppy steering.

Very good too hear. Things are looking up. Wish I could say the same for mine. I'm awaiting a new ECM. Gonna be at least a week with no truck. :(

Your C20 has an ECM?

Edit:
Oops I forgot the C/K ran through '87

Not in 73 it didn't haha. But I built a TBI performance 355 for the truck. Bored 350, with a lot of upgraded goodies, nothing insane but efficient and effective, power when needed, mpg when not, 365hp/425ft.lbs (about, hasn't been dyno'd. No where near me to do it.)

Okay that makes sense.

My new truck is the first for me in a long time without an ECM, PCM, VCM, WXYZCM and I love it.
Carb is running a bit rich right now and I have to relearn how to tune using hardware rather than software.

Haha. I accidently built the engine that doesn't like carbs. Tried and tried my best to get it to run and was never pefrect. Put TBI, thing runs like a top.

I have nothin against carbs, I like them. Just this engine doesnt lol. I work at a dealer so I know what you mean by computers, need some kind of module just to pick your nose and another to tell you where to put the booger hahaha.

Good question. I am trying to figure out the color.

The RPO sticker in the glovebox says RPO 117L  17 Saratoga Silver
Everything I have found so far tells me 1975 Chevy Truck paint code 17 = Medium Graystone.
