When replacing the pin box on your trailer, you will want to consult the spec sticker on your existing pin box to find the model number that you're currently using, as you will want to use an exact replacement. The Reese Sidewinder # RP34FR you were looking at is designed to replace some fairly common pin box models listed below; if your pin box is one of these then you can use it as a direct replacement. If you check your pin box and it has a different model number, just let me know what model you do have and I can see if there is an alternative available.

RP34FR replaces:

Fabex 663 and 665
Lippert 0719, 1621 and 1621HD
M&M 663 and 665

If you can't locate any model number on your existing pin box, you can measure the bolt spacing to determine the model number. I've linked one of our helpful article that shows how and even gives a chart that shows the different measurements on potential pin box models.
