The Lippert 1716 5th Wheel Pin Box, # LC1324791 is is 12.5" in width. The Lippert 1621, # LC1387883 and the Lippert 1621HD 5th Wheel Pin Box, # LC1191151 are both 12" in width.

The easiest way to replace your pin box is to find the pin box's manufacturer name along with its specific pin box number. These are both typically located on a sticker on the pin box or on the king pin itself. This pin box number will usually be 3-4 numbers long and can have letters attached to it. Some very common pin box numbers are Lippert's 1621, 1716, and 1116 pin boxes. Or, you can contact the RV manufacturer along with your 5th Wheel's VIN to know what was originally installed.

Another option is to measure your bolt pattern and match that against the reference guide I have attached. The steps to do so are listed in the help article.
