70 duster 8 3/4 conversion to 4.5 drum or disk hardware

Many owners - myself included - have the original A body SBP 8 3/4" rear setup with the rare bell drums that look to be no longer available.

My thoughts are I would consider contacting Doctor Diff - Cass - who is the Mopar guy - when it comes to A body SBP 8 3/4" alternatives, including rear axle availability, swapping to 4.5" bolt circle, upgrading to rear discs, etc.

I intend to subscribe to this thread to learn what's available out there.

Keep in mind --- the Abody SBP 8 3/4 " backing plates are unique, and any rear brakes have to take that into consideration, unless you intend to locate and use other backing plates. The Bbody backing plates are getting hard to find in my area.
