If anyone out there has the newer style flap that scoops the snow up onto the track for cooling in hard pack trail conditions they want to sell. I have the small style one that came on the 503's It looks nice but it doesn't do crap for cooling the sled on the trails. I'll sell mine or trade it and money for the new style one. That's you lucky guys out west that have unlimited powder and only have to worry about keeping the snow off your ***! I attached a pic of mine.
