Dbone,
This is probably not an "approved" method, but I put a bunch of 2X6's across the rafters in my garage to spread the load. My cab was stripped, doors, dash everything, so it was not heavy. I used a tow strap and a come-along and raised it above the frame and then wheeled the frame out from underneath. The box was already off so rear clearance was not a problem.
Again, I would stress that I would not put much more weight than I did on my rafters and did it close to the wall...I was able to do it myself and did not need the help of neighbors. My cab was rust free and strong..if yours is full of rust, again, I would be careful as to not bend/break what you have left.
