Hey Everyone! I just bought a 1978 GMC C15 High Sierra for $1500..It has a new 305 Crate engine that has about 38,000 miles on it. A rebuilt 350 turbo auto trans, new radiator, working heat, new carb, a new front end, kenwood cd, 6x9 rear speakers, a sub, mtx box, and probably a bunch of other new stuff. The guy I bought it from had bought it from his cousin who was got a divorce and couldn't keep all his projects anymore. I just haven't went through the receipts of all the new parts that he left for me. So needless to say its a strong running truck that I can work on and drive for the winter instead of my mustang.

So that was the good...The bad is the driver floor pan is rusted half out, the defroster doesn't work, the rear bumper and tail gate have surface rust, there is some rust in the driver side front wheel well near the bolts, and the dash lights don't work

So far I haven't found much diagrams on wiring for this vehicle so if anyone can direct me where to find that I would greatly appreciate it. Im not exactly a mechanic but Im great with electrical, body work, and a extremely fast learner.

So far I have order an h4 headlight conversion kit to make the truck more drivable at night and a driver side floor pan to.

Here's what's worked for me...change the oil before you go, take the interstate and "blow it out" real good on the way -- get it good and hot, and make sure you go when there's no line -- you can just drive right up and go through, so you don't have to idle for long. But if you're putting up 7s, you might be needing a new catalytic converter. Good luck!
