Nice question, I have some information for you below:
First thing you need to do is figure out why style of pin box you have. Pin boxes are not universal and can be different from unit to unit even if the camper came from the same factory.
If you look at your pin box there should be a plate or sticker on it that will tell you the type and style of pin box. Some of the common types are Lippert 0719, 1116, 1621, 1621HD or a Fabex 665. If you cannot find this information you can call the manufacturer and give them the VIN. They will be able to tell you what type of pin box was installed at manufacture.
**Curt Flex Air 5th Wheel Pin Box - Lippert 1621 - 21,000 lbs # LC369535.
This unit will replace any Lippert 1621 style pin box so if your determine that your RV takes the 1621 style it will work. If it is a different style I can help you find the right replacement to match.
I have linked a very informative help article that will walk you through the process step by step in figuring out what style of pin box you have. If you have any more questions you can reply to this email and I can help you further.
