has anyone installed the slp vent kit on their xp. my concern is the left front (shock vent) part number 32-564. i`m somewhat hesitant to cut out location for this vent because it is not on the side panel itself. it seems vunerable to projectiles thrown from the ski? it is combined with metal backup grate on the inside and requires drilling out the rivet that holds the clutch cover bracket in place. when i pre fit and form this vent, i have to twist the thing to get it to set flat. has anyone successfully installed this thing and how do you get the drill bit through the maze of a-arms and stabilizer bar? any suggestions or tricks would be of great help before i hack a hole in my new machine! thanks
