It's no secret that you can use 4x4 posts and cement blocks to get the body up off the chassis. Lots of guys here have done it or are doing it. I could not get my body rear high enough to roll the chassis out so I used rims with no tires and also removed the rear shocks and coil springs. A floor jack and some big blocks of wood or just a cement block will jack up the body just fine. I have a bad back and did not strain at all. On my other SS, I used 2 wheel dollys. One under engine cradle and one under rear axle center section. I could have got the body higher doing more blocks but the heavy angle doing one end at a time was getting pretty scary
