There are a lot of bolts to remove, but only a few welds that have to be cut. They are on the rear stake pocket where it meets the floor, both topside and on the underside. The welds on top are relatively obvious, once you scrape away the body caulk. Underneath, you just have to look carefully at the location where the floor joins the stake pocket. A good cutoff wheel or even a reciprocating saw will do the job. Good luck!
