Jireh Cycles has great pricing and free shipping on orders over a certain amount. Also, discount cycle parts.com has great pricing. Lowest I could find. Only issue on this site is you need to go to the Drag Specialties fat book or custom chrome catalog to get part # then type it in the websites search engine to find it. But pricing on both sites is really low and they have alot of stuff you can buy. I am sure one of these sites has the parts you need.
HDWRENCH would be my choice to buy from as the price will be fair and the service is second to none you almost can't put a price tag on the "after the sale help" that some don't offer, and I would pick his brain on Heads either from him or Dewy
