I have a 1989 Polaris Indy Trail with a P85 primary clutch. The cam arm bushing are worn out and I found out that Polaris does not sell the bushings seperatly like Comet or Arctic Cat. I heard that the ones for Arctic Cat have a O.D. that is too large. Also that the arms are exchangable between the Comet and Polaris clutches. My question is does any one know if the Comet bushings have the same O.D. as the Polaris bushings?
