Most ignition key switches have a 'D' shaped body so they don't rotate when you turn the key. However, most people don't have the necessary D-shaped drill bit, so we made this convenient, universal bolt-on ignition switch tab out of 1/8" thick stainless steel and then tumbled them to give a superior fit and finish. You can run these as-is, paint or polish, whatever floats your boat. This tab accepts any ignition switch with a 3/4", D-shaped body, such as the Cycle Standard Deluxe 3-position Ignition Key Switch
. The mounting hole accepts any 5/16" diameter bolt. Made in Ohio, USA.
