I'm always terrified of buying anything from eBay or where ever because I never know of I ordered the right thing. But I'm looking either for a replacement shock tube or a rebuild kit. I don't know how to do a rebuild. But putting the shock in seems simple. Either way I'd like both options and if I decide to do it I'll give it a shot if not I'll have to find a local shop. I'm sure Polaris will want my first born and maybe a left testicle, so I'ma try and avoid them as much as I can.
