I usually get OEM stuff from cascadeinnovations.net. I'm usually ordering parts from them anyway, so I just get random parts that are prone to wearing out or me losing them. Case bolts for random sets of cases I have laying around, idler gear washers and lock rings, those little steel alignment pieces for the side covers and cases and cylinder alignment thingies, clutch cover bolts, clutch cable holders, frame nuts and bolts... blah blah blah. You can get every single part for the banshee from their web site.
