I bought an '04 F350 Dually three weeks ago. It has a hideaway in the bed that has a kingpin hitch with a threaded hole on the top so you can pull it up into position. I remove the kingpin from under the bed of the truck by removing a cotter pin, then pushing in on a springloaded cylinder that presses on the kingpin to keep it from falling out the bottom. The kingpin drops down after removing the hardware. Any idea where I can find the replacement gooseneck ball for this system and do you know if this is custom or if it's a manufactured hitch? I've attached a pic.

Thanks,

Jas

Wish I knew, havn't seen that one before. B&W has a king pin that will fit into the turn over ball socket, but it just has a hole in it.

I am still looking also
