I have noticed that a lot of people are having trouble finding a winch mount for the newer sportsmans. Since I have two 2010 500HO's I just finished dealing with the same problem. Polaris wants you to buy the warn polaris combo. I ended up buying a winch mount plate for about $21 and the roller bracket that goes around the winch for 19.99 at my dealer in El Campo. They didn't even know what to do at first they only showed the combo. They called a contact they had at polaris and he spit out some part numbers and now they are planning to keep the parts in stock.
Hope this helps

 

I'll get you guys part numbers as soon as I can

 

You can also buy just the Warn mounts by them selves too. Check them out!

 

Good to see "Montana Jack's" on this forum. The've got a great place & lots of stock.
