Hey Paul; I just reached out to Lippert with that number and they are unable to identify your pin box. If you can get the serial number or RPO number off of the tag on the pin box they will be able to identify the bolt pattern. If you know you have a 1621 bolt pattern then you can switch it out with the # MR64VR (aka RPB72-1621HD-03 for trailers with up to 11,500-lb GVWR) or # MR74VR (RPB72-1621HD-04 for trailers with 11,501-lb - 14,000-lb GVWR).

Hey Paul, were you able to confirm the bolt pattern on your Lippert pin box? Knowing that would show whether the MORryde pin box was a good match for your Columbus fifth wheel. Your update could make it easier for others trying to replace a similar setup.
