Here is a CLUTCH CROSS SHAFT BUSHING KIT for your 55-57 Chevy. Everything about our clutch cross shaft bushing is custom. The bolt is turned from raw stock, case-hardened and plated with black oxide to protect it from rust. We've specified a bright plated, corrosion-resistant lock nut that features a nylon insert to hold it in place. The heart of the bushing kit is the two bushings, custom-made of Delrin, a high-tech material designed to provide smoother movement and greater durability. Made in the U.S.A.
