Try Clymer's. I'm not sure how to contact them but they have an ad in every Magazine.
I have an 91 Indy RXL and they were the only ones that had the manual for it. They may have other stuff nobody has. I tried a couple polaris dealers around Seattle and nobody had one but they wanted me to order a Universal one from Polaris for like $85 the Clymer's was $35.
