So I have my '56 Olds (four door Super 88 sedan) stripped down and ready to media blast. With the car at this stage, I know the best bet is to pull the body off the frame and put it on a rotisserie for blasting and painting. I don't have floor lift or an overhead crane set up, so I was considering using railroad jacks, etc. to support the body and roll the frame out. I know at least a few of you have done frame-off's and I'm curious what your "technique" is? Most importantly, is it necessary to weld in cross supports in a "post" car (sedan) with no doors, glass, etc?
