Just wanted to pass on a little bit of information about a change in the Revs rear skids from 06 to 07. BRP dropped the front arm mount 1/2 an inch lower in the tunnel and subsequently extended the 07 rails 3/4 of an inch to the front tip. So if you try and install the 07 rail into the 06 or older chassis the tips of the rails and the drivers bind when the front shock is compressed. I checked with the local dealer and found that the rails for the 06 are a different part number then for the 07. Hope this info saves someone some grief.
