When I bought my 93, it came with most the parts of a 5th wheel setup. It was missing the hitch and rails, but the frame points are still bolted to the truck frame, as well as the holes in the bed. I'd like to use what's there to run a gooseneck plate, versus cutting more holes in the bed.
Where would I find the rails, who makes em. I'd like to find ones that fit what's there, don't know if the setups are universal, or truck specific. If I remember right, it was like 18in between the holes, front to back, and 38-40 left to right, but I'll measure for exact dimension's
