Best replacement for worn clutch

Hello,
I need to get my SP500 non EBS ready for snowplowing this winter. I checked my primary clutch and the weights are worn and outer sheave is grooved. I can get a Caltric clutch on ebay for about $110, but didn't know if that is the best option or if it will handle snowplowing well. Can outer sheaves be found or will aftermarket clutches last fairly well?
Thanks!

Starter solenoid problems

Can someone out there please show me where the starter solenoid is located on a 2017 sportsman 450 HO ? Pictures would help. Thanks in advance.

Rear top shock bushing

Yesterday I was replacing the wheel bearings on my 570 and putting on HD springs. I realized that the rear shock by the exhaust had a loose bushing. I had to go to the dealership to get wheel bearings anyway, so I asked them if they had bushings for the shock, and they said Polaris only sells the whole shock? Has anyone had this happen? Does anyone know if I can get a replacement bushing? Thanks
