Ok, I have a 1990 Blazer that is rusting inside out. The cab mounts are rotted and the body is starting to sag. I was wondering if a '87 or older full-size truck cab would bolt-up to my blazer frame. Is it possible that the blazer frame is actually a short bed truck frame? I am not to worried about the bed right now. Has any body done this before? Any input would be appreciated.
