My wife has a 99 Blazer 4DR 4WD, 4WD doesn't work, I don't want to look for the problem anymore, and we can't seem to sell it unless we give it away plus we really don't need 4WD. SO we want to turn it into a playtruck with a smallblock. I want to put a 2WD frame under it. Could I use a 2WD frame from a second gen 2DR? Or does it have to be from a 4DR? Could I use a first gen frame, if so which one? I understand frame ends are different on a first gen, and I have no problem fabbing bumper brackets.
