Hey Ken, the fits are all based on the pin box they are designed to replace. So if you can get me the pin box model from your fifth wheel that would be the easiest. Most likely it's something like a Lippert 1621. Or if you can't find that a good portion of the time we have figured it out based on the model of the camper as well so you can get me that.
The part # GY38FR for example fits in place of the 1621 pin box.

Found this hitch a wonderful upgrade I did purchase a weight class above my pin weight for longevity purposes, but don't notice any adverse chucking or harsh ride,love it!
