where can i find a smaller supercharger pulley?

Does anybody know where i can find a smaller sized pulley? I have seen diffrent kinds for other cars, are they universal, or does Ford make some especially for SC's. I am only 16 years old, so don't make fun of me for not knowing much about this stuff. LOL

You can find the smaller pulley at www.mn12performance.com and www.supercoupeperformance.com you can also get the pulley from embree. Before you do any kinds of mods to the supercoupe I would highly suggest to open the exhaust up first or you will be facing the notorious blown head gasgets. Hope this helps you out.
