Well ironically I can go pick up a '69 2wd PU for $100 if I want it. It has no engine or trans but the body is supposed to be good.
Honestly I will have to sit in it and see how comfortable I am in a standard cab where I can not move the seat back as far as I can in a sub/blazer.
That is a pretty good idea though... I could also cut down the bed on the 2WD and have a stubby bed on a blazer frame, VERY COOL!!!
