Looking for seat covers for both of my sons snowmobiles. One is a 1999 mxz 600 (ZX chassis) and the other is a 1997 mxz 440 (S chassis). The seat covers I'm looking for are the ones which are mostly yellow with purple Ski-doo on the sides as well as yellow and purple checkers along the sides. I've found some "ZX" chassis ones on the auction sites but it gets hard to find the "S" chassis covers. The S chassis sled also has a gas tank cover which is yellow and black available for it, so if anyone has what I'm looking for, just respond in here or PM me. If someone has a link to where I can buy these, that would help too. Thanks for looking.
