Re: Dad's 1979 GMC Heavy Half Transformation

If you caught the change, I was planning on bringing the truck home and do all the finishing work myself, but since Jayson talked me into swapping in the original parts (engine/trans and everything associated with that), I've ignored the 78 build for almost a week now and have been on the search for all the scattered parts for the Dad's 79 GMC. Believe me, they are everywhere, in boxes, buried in cabinets, in the attic, in the barn, in the basement, in bags, tubs, you name it, it's everywhere. The rear end is finally complete, however, I will re-work my 56" HD springs by removing a few leafs and putting them under the axle and bolting everything together so that it'll make swapping the rear end quite easy, of course I'll put on the wheels and tires. Here are a few pictures of just a few of the items I've run across. Still looking for the gas pedal!!!!!

Pictures:
1. Rear end parked for now behind the 78 cab.
2. Found two GMC horn buttons, this one is pretty damn nice.
3. I had two core supports up in the garage attic, this one went to the blaster today along with three 7" rally wheels.
4. Brake Pedal and Parking Brake assemblies need cleaning!!!
5. Power steering pumps. It's amazing the differences. Far left = 78 w/AC, middle = 79 w/AC, far right = 77 w/out AC. 78 and 77 have the same pump. All three have different attaching brackets. Destroyed the 79 two-groove pulley trying to get it off and was able to get the two-groove off of the 78.......!

Thanks Mike
