Since you want to restore it, can you just leave it on the truck and do your cutting/welding in place? The good thing about a dump bed is, if you raise it up, the frame and axles are almost all exposed. I get nervous working under a raised bed and always triple block it up. Don't rely on the cylinder to hold the bed up if somebody will be under it.
