It's custom built. The only factory part is the receiver itself, which is a Reese. It was loosly patterned off the Reese hitch off my Dads '88 3/4 ton, then sized to fit the '55 frame width. The cross tube is 3" square, side plates are 1/4", all TIG welded. I used existing holes in the frame (2 factory, 4 from the original homemade hitch that was on it when I got it) to mount it up. It also has a universal 4 wire trailer harnes on it as well. The hitch plug is custom made as well. 1/4" stainless, sized off of a Kodiak truck grille emblem. I'm also using a spare tire carrier from a late model C 1500, the winch type, so there's no interference there.
