I have a pair of NOS replacement outer track belts for a Vintage Polaris 37 Cleat Snowmobile Track. They measure approx. 2 13/16" wide. They don't have the X's on them. They've been stored in a building for quite a few years and have some marks/light scuffs and a little bit of soiling on them. Vintage Polaris Snowmobiles that used a 37 cleat track include 1970-1975 TX Models, 1972-1973 CHARGER Models,. 1971 CHARGER with slides, etc. If your track has a decent/acceptable center belt section, but the outer belts are in bad shape, here you go. A call or text message is best. Thank You. Jonah
