I am building an '85 extra cab. The bed is in rough shape. I am having trouble finding a replacement so I am looking to install fiberglass sides from Downey. My question is do I have to use a toyota doner bed, (the bed currently on the truck; both floor and bed supports are rotten) or can I use a bed box from like a Ford Ranger splash bed (which has fiberglass bed sides). I may be able to find a 3rd gen bed to be used only for the frame and floor. Any suggestions, or have any of ya'll used or known anybody who has used a diff. bed box? Thanks
