removing body frame
 

I have a good frame, drivetrain, glass and suspension. The body is shot(rust) The roof is beyond repair. How do you remove the frame from the body? I want to replace my body with one that is cleaner.

73 Ranchero. I will be looking at the junk yard for a good shell.

I woud prefer to find a shell that is not in ajunk yard but they seem pretty hard to come by so this is my next plan of attack.

I have also though about swapping my engine and trans into a 64, would that work?
