I bought a reverse kit that was in a '93 Indy 500 and i wanted to put it in my '91 Classic. I had a buddy that told me he wasnt sure, but thought that I couldnt because of the jackshaft being different. Can anyone confirm if I can do this swap, and does anyone have any guidance. I have the whole chaincase, gears, and reverse linkage to do it, just want to make sure I can or not. Thanks!
