I believe the "Part Name"/"Description", on BikeBandit.com, is proper Honda terminology, though the P/N may not be. Try printing off the schematic (right-click the image, "Save As", etc.), and the page with the Description and P/N, from Bike Bandit's site, and take them into your local parts shop, and show them what you need. They will be able to order it with the information you provide. If you plan to order directly from Honda, then you may need to call and speak to a Human Being. Cheers!
