That 5/8" grooved pulley should fit the belt width, but the 2-1/4" diameter is smaller than the original pulley. A good thing as it will spin the alt faster than the generator, making it charge better at low RPMS. The stock fan belt may end up being a little long, but since you are swapping in an alternator with a custom bracket, the belt length most likely would be off, anyways.
