There is always Rabers out here in the bay area. They are down in San Jose. They are not always the cheapest, but they usually have what you need, and are pretty helpful. If you go into the shop they will let you go through the parts, new and used, or help you find what you are looking for. They will also give you credit for stock or custom stuff you bring in, buying them out right, or trading for the parts you want from them. I know Bruce, from Hollywood Bobbers, is comming out with more and more top notch parts too. He is a stand up guy, and has helped me out a lot with my triumph. He is out of the south San Francisco area.
