I have a 1951 B3B undergoing a full frame off original restoration. Does anyone know of a structural diagram that shows types and dimensions of all the correct structural members that comprise the bed? I need to find out how the bed sides, bed front panel, bed wood, and all underlying structural members were bolted (or welded) together. I also want to find out what the exact dimensions of the underlying structural cross members and sides members were that hold the floor boards, side panels, and front panel together into one unit. I guess I'm the kind of guy who likes originality and doesn't like to slap things together because it's cheap or easy.
