I was just BSing with my local wrecker, after he destroyed a gorgeous slider top on an '85 K5 that I wanted, and found out when he forked and lifted the truck (he pokes the fork through the windshield and lifts the trucks that way), the frame/drivetrain stayed on the ground!! He said there were a couple little places that were still hanging on, so he walked around with his torch, cut, and just carried the body over to his crusher once fully free... Then stripped and cut up the frame seperately... Damn good interior I wanted on tht truck, too.. So fix your body mount rust!!! I was laughing pretty hard until I looked at mine!!
