Secondary dropped a rivet, wreaked havoc on my sheaves!

Hey guys,

Long time lurker, first time posting. I have a 2010 700 Grizzly, I was doing my spring maintenance last night and pulled the cover off the clutches. Lo and behold, the secondary dropped a rivet causing quite a bit of damage to the sheaves and the belt (I’ll add a few pics later on). I spoke with a guy at one of the local shops here, he figures they can machine the primary sheaves to fix em up a little bit and get them usable again. But the secondary is pooched. Any of you guys have a line on good used secondary clutches anywhere? Not having a lot of luck with Google and eBay. Any help would be much appreciated!
