On your suggestion I did check Western Cycle Supply's web site. Which is, frankly, horrible. No clutch parts came up in a search, just handlebar levers.
I compared the price of another item with the same on Hitchcocks and there was virtually no savings other than the probable shipping cost.
Hitchcocks does such an amazing job, has a fabulous web site as well as a beautiful and easy to use catalog it will take much better pricing and/or a vastly improved web site to get my business.
