Manufacturers do not list the pin box bolt patterns that they use so you will need to look for the tag on your current pin box, which will have some serial numbers and RPO numbers that we can cross reference. If your tag has worn or away or been painted over then you can use the attached guide below to determine the bolt pattern.

Once you know the bolt pattern we can find the corresponding Sidewinder pin box for your 2004 Fleetwood Terry Quantum 5th Wheel Trailer.

For example, the Reese Sidewinder 5th Wheel King Pin with Rotating Turret # RP34FR that you were looking at fits the following bolt patterns:

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