Those parts are ancient. They are not manufactured anymore period. I called performace machine, and Russ told me flat out, that design was 'Purged' from their system years ago....and I have been going back and forth for years with the people mentioned on this forum, but they do not have any of these old rotors. The closest match for rotors on our older Pitbulls are Bikers Choice Mirrored Rotors. Or you can just use Harley rotors, but they wont match your wheels at all.
