Buddy,
I used ther same 12-step procedure. Except, I used two 6x6 timbers across the bottom to hold the truck up until the frame was rolled out. This was before my new garage bay was completed/envisioned and I had only one inch to spare (before hitting ceiling beams)
Then the timbers were trimmed to fit under the body and were aligned under the front and rear frame-mounting holes. The body was lag-bolted to the timbers through the frame-mounting holes. This allowed me to attach the two cross-timbers to wheel-dollies, which made it easy for one person to move the body around (I now wish I had taken pictures).
One thing I learned is that only having two supporting beams put a lot of strain on the body. Do not do your finish bodywork until you have the body back on the frame for a few weeks. A week or so after I put the body back on the frame, stress cracks appeared between the rear of the front doors and the roof line. The leaded seam in those locations flexed and cracked the epoxy primer. To be safe, we removed the primer and a lot of the lead, and then filled with Evercoat Metal-2-Metal filler. It has been a little over a year with no problems.
