I have a 144" x 16" from an '07 Summit Adren., in really good shape (no paddles missing the last time I looked); will need to be converting my drivers to 2.86 so the 2.52's I have are available as well... Let me know if you are still looking.
Iv got a stock skidoo 144x16 track on my sled right now. its only got less than 200 miles on it. but im looking for a 159 to put on it. id sell it providing i can find a 159.
