Then you need one! Saw your post that the old one was stuck on a bendix that you removed? If so get a new one as the bendix could damage the case over time without this bushing,plus cause engagement and rattling problems.
If you can find an after market one this size good luck.. I never tried because I had a box full of them at the shop. But on this I'd be careful! Must be the right size,not worth taking a chance on cracking an engine case for a blamed bushing.. Again ebay is cheaper on these when you consider shipping charges from Cycle Parts Warehouse,Partzilla,etc.http://www.ebay.com/sch/i.html?_nkw=...493&mfe=search
