This is the donor truck. It is a 1970 CST 1/2 ton. It has the factory 402 big block, turbo 400 auto trans. It is complete except a couple of the factory big block A/C brackets.
The engine bay of the donor truck. Everything you see will soon be on the 72 blazer.
I am also going to install a factory posi rear end that I have acquired over the years.
