I thought someone might find this page to be useful... it's a supplier directory where you can pick from a list of about 100 categories (like engine rebuilding, mirrors, LEDs, air horns, etc, etc.) and it gives you a listing of companies that sell those products. Click on the company name and you get a summary of what the company does along with a link to its web site.
