Does anyone know of an online site that will list parts diagrams for 83 Polaris parts....so far the dealer only went back to 85 and I don't want to chance ordering the wrong parts. I need track carrier wheels and possibly a new clutch. I have a clutch from an 81 and an 82 (or 84) but they do not look exactly the same as the 83....does anyone know if the outer piece (where the belt rides) can be interchanged with different years?
