Hi all, I'm looking at starting my replacement of the full rear frame rails on my 64 1/2 mustang this weekend. What are some of the best ways to support the car up off the ground since I will be taking out the full rear frame rail on each side one at a time? I am dropping the rear axle out of the way and am installing new rear floor pans w/dropoffs as well. Any information on the easiest way to keep the mustang supported well so it wont move shape and stay level while i replace the rails will be great. Thanks.
