Ok the pulley I ordered won't work the groove is not wide enough. Does anyone know if a 1/2 inch bore will work the bolt is 12 mm which is like 0.473 inch.
That was my first thought but the pulley is so narrow that I would have to use a belt that is only 1/4 inch and I don't feel that is big enough to trust itGet a narrower belt & a matching pulley for the alternator.
