I own an 81 blazer and the rust has finally gotten to me. I replaced the rear tailpan and floor awhile back but the body is failing in other places and is getting unsafe. I would like to put a pick up cab on the frame and make it a short-short bed and I'm wondering if anyone knows whether or not a 70 chevy cab will fit the body mounts in the same way an 81-87 is supposed to.(Yes I know the rear two mounts will have to be fabricated) Any other info about the switch would be appreciated too!?
