I actually changed the track out on mine, put a studded one off an 800 that I had on it, (my oldest daughter then learned to ride on the 900 that year, think I sold it a year or two later to a member here) and now that you mention it, I remember the coupler. I called Krom while tightening it to make sure I had it locked. No, firecat's never had that crappy setup. They had the lonnnnng bolt, not sure if the last ones ever had the short bolt like all of the later sleds had or not, but I don't think so.
My 04 was the blk/red one. Great looking sled.
