I'm looking for a spare drive clutch for my 2013 Pro RMK 800. I had an incident were I got flipped on my left side on a climb by a rock that wasn't as deep as I would have liked and ended up grinding up a drive shaft cover. Luckily we were able to drive to a nearby town and get a hold of an un calibrated clutch. I know its considered a P85 clutch which Polaris has used for a long time but are they all interchangeable. If i'm looking at them is there a way to tell which ones will fit.
