Of course the correct way would be to remove all the bolts through the body blocks and jack up the body in the rear. This would entail unbolting and removing the rear fenders and the bolts to the rear bumper vertical supports. I don't think it is a real hard job, but it would take an afternoon to do. I think you would only need to jack up the body about 2" or 3", as the U bolts will slide out at a slight angle.
