[77ChevySharkBite]

budget78gmc truck is awesome actually looks almost identical to the one I just bought myself just mine is a 77, look at the pic. I'm in your same shoes though man it has a rebuilt 350, and everything is awesome the people I bought mine from bypassed the heater core, how I don't know but they did. I'm first going to knock out the body work, and my bed is dreadful looking too rusted fully, and even has some holes in it, but its okay I either want to plexiglass my bed, or put a wooden bed then a 1/4in of plexiglass over it to help preserve it some.

Good luck on the truck can't wait to see the finished product, I'm attaching my truck below.
