Hi all,
Are the location of the lock and ride holes all in the same place on all polaris atv’s?

The reason I ask is that I can purchase a used rear box for a good deal that is currently on a 2008 Sportsman 400HO (same as the hawkeye) but I would need it to fit my 2011 sportsman 550 xp. The model number is 2875678 and on ebay it says it does not fit my model but I am not sure if this means it is not designed to fully utilize that rack/bed or if the lock and ride holes are in a different spot.
The seller said holes/plungers are approx. 29 1/4"apart from center to center but my quad is in storage now and I can’t get to it to measure mine.

Thanks
