A set (2) of chain adjusters Bushes for the Bevel Drive 900ss, 750ss and 750 Sport/GT Ducati Twins of the 70's and 80's. These chain adjuster Bushs fit in the swingarm tubes unlike the 860 GT/GTS and Darmahs where the Eccentric Chain Adjusters are in the frame. Newly Vapor Blasted and ready for use. I also have Swingarms, Rear Drum Brakes, Covers and other bits for your Ducati Bevel Drive Twin.
