The Reese Goose Box Air Ride Coupler Adapters are going to replace the Lippert pin box on your Fifth Wheel so the hole spacing on the brackets is pin box specific. Your existing Pin box should have a sticker on it that tells you the Lippert OEM pin box number. Common Lippert pin boxes are 1621, 1621HD, and 1716 so you would want to choose a Goose Box that fits the bolt hole spacing of your particular pin box.

If you are not able to find a sticker then you will need to measure the bolt hole distances. I have attached a help article that shows all of the measurements that need to be taken in order to figure out which OEM pin box you have. The Spacer kit part # RP61301 is for pin boxes that measure 12-1/2 inches wide. The spacer increases the width of the Goose Box to allow it to fit where the 12-1/2 inch OEM pin box used to install.

If you are able to find a sticker and it does not say the pin box number, please send a photo of the label and I can try to determine which box you have.
