Most of the body bolts sheared off, even though I used tons of Liquid Wrench and PB Blaster. I have yet to drill and tap the bolts out, and that is the part that bothers me the most right now. We supported the body on landscaping ties (roughly equivalent to 4x4's) and concrete block. We had to go 3 blocks high, with a few layers of brick, to clear the rear wheels and frame. We also let the air out of the rear tires. In the end, we had about 4" of clearance.
