I got mine at a local electrical motor rebuild shop. The wiring is super simple. The guys at the shop showed me what to do since I had an external regulator (ex FHP car). You will have to grind down the bracket by a very small amount. I did it with their grinder in their parking lot. Its a 15 minute job. Just don't be in such a hurry that you forget to disconnect the battery. I did that once. When I dropped my hot wire off the back of the alternator, it almost welded itself to the fuel rail!
