Ski Doo makes a nice accessory set of scratchers http://store.ski-doo.com/product/0/860200444/_/Ice_scratchers for the XM/XP. After putting them on a XP I wondered if they will fit the REV. After completing the installation on a 2005 rev I can confirm with very modest engineering they do indeed work on the REV. The only thing you need to do is make a spacer to adapt the holder bracket's attachment point on the tunnel (where the wire is held up in the non-deployed position). Everything else is very straight forward.
