Ok so I have a slightly better Idea what's good and what's not. I have some rear shocks and powderhound skis for sale from 2015 RMK.
2011 800 engine with 600 miles on rebuild
Primary & Secondary clutches
2011 chaincase, jackshaft, and driveshaft
2011 seat and fuel tank are also good.
I hate to say not much else is good at this point. Damage is slightly worse that originally feared. There may be a buttload more as I haven't gotten to the assault bulkhead yet, and I'm scared to see the condition. If there is anything you need, ask......
