Available for purchase is a 6 Bolt Rear Disc Carrier for Wire Wheels (not drum brakes). Had on my vintage Ducati 750 desmo racer but now I am using mag wheels and do not need it. Nice conversion from drum brakes to rear disc and caliper for the early bevel drive Ducatis. Could work on other Marques but do contact your local Dealer or race shop to confirm the fitment to your application.
