I don't know if ducks still selling them ( he's riding an XP now), but when he was they went for 50.00. There was another guy selling spacers for a while that were a bit simpler for 25.00 but he's not been on e-bay lately.
A couple washers and a new bolt and you can float it for under 5.00, we did a riding buddies last year this way and I just did mine last week. Found everything but the bolt laying around the shop.
