I got my crank pulley at an alternator shop, if thirty bucks is a good price. I doubt that though. I used a new v-belt alternator. After I measured I came up with 2.65 inches as the largest pulley I could use and still get the inner cover bolt passed the pulley. People will jump in and say that is not big enough. I don't live in the city though. If you plan on being stuck in traffic for great length's of time with the headlight on, I'd say go bigger. I raised the idle to 1100 rpm to help with the charging rate at idle.
The problem is, there is no standard pulley, and depends on the alternator pulley you use.
