I finally finished up the rearsets for my 77f. Since only one company makes bolt on rearsets for the 1977 cb750f I worked with my good friends to make these happen. Me and branden (has a amazing 78F) mocked everything up how it needed to be to function correctly. Our good friend Jim put his garage machining skills to work and made us some one off brackets that had a hanger for the new Brembo master cylinder complete with heel guards. I decided to go with a set of the new Joker Machine universal arms, Thanks for the link Branden!
