I happened across a 1995 Polaris 250 Trail Boss today. The machine was in excellent condition with the exception of the motor which the owner explained to me had seized up and the crank was shot. I've looked around and have found several lower ends but not of 1995. How interchangeable are they and if so what years will work? I pored through the free manual on this site but it doesn't go into particulars about year to year compatibility. Thanks Mike
