The PO of mine just cut out for a tailgate and put angle iron around the edges then just made his own tailgate with angle iron and some aluminum diamond plate. Its a little different but functions for as few times I have ever needed a tailgate and its one of the few mods he made that I didn't change.
He was very creative on some of his mods. I think he had more time and raw supplies sitting around than money. He made his front bumper with some c channel and a twin bed frame, made his own trailer hitch and rear bumper with angle iron, and a side mount for the spare using angle iron and some flat steel he welded together. My dash was made from spare aluminum diamond plate and the seats he had installed were held in with sheet metal screws. Yeah and somehow he ripped off the skid plate on the oil pan, nothing some screws and a lot of orange rtv couldn't fix.
