    Frankly there are very few options for 3/4 pulleys, but that's ok - when the one available works why reinvent the wheel? The only thing to be careful of is once installed, make sure it's aligned horizontally so that the belt either is completely directly in line or pulls away from the alternator a bit - I off and was hitting the alternator fan, now that it's so close to the body.

    I'm converting a 49' Ford F3 truck from 6volt to 12volt and needed a 3/4" alternator pulley to make it work with the existing flathead six engine. This pulley fits a GM 10si alternator perfectly. Shipping was nearly instantaneous and was up and going in no time.
