There are a couple of different ways to determine the pin box you have to see if you can switch to the Reese Sidewinder 5th Wheel King Pin with Rotating Turret # RP34FR.
The easiest way is to try and locate a sticker or placard somewhere on the pin box itself with an identifying mark, or you can call the trailer manufacturer with your VIN.
If that information is not available for some reason, you are going to need to take some measurements to determine exactly what you have. I have added a link to a help article called "Measuring to Determine the Correct Replacement Pin Box for a 5th-Wheel Trailer" which has the exact measurements you need to take, and this will allow you to find out what pin box you have.
Sidewinder # RP34FR will replace Lippert 0719, 1621 and 1621HD, Fabex 663 and 665, M&M 663 and 665, along with Lippert 1716, 1116, and 0115 pin boxes, though the Lippert 1716, 1116, and 0115 pin boxes do require the Spacer Kit # RP97FR.
