1970-1975 Swing arm bushing replacement: If your swing arm has dimples like these you will have to drill them out in order to remove the bushings first. You can hammer the old bushings out or use a press. Depends on how handy you are or if you have the tools. New bushing should go in with mild tapping if the inside of the swing arm is cleaned. Apply liberal grease to the metal part of the new bushing.
