We now offer a BBP disc upgrade for 1973-76 "A" Mopars that use the large Cordoba 11.75" Ø rotor. This is a simple bolt on; no swapping arms or spindles and you can reuse your stock bolts without redrilling.
This uses the 1990 style Chevy calipers with internal sliders, and a new HD version is shown above that uses the Mopar 2-3/4" Ø piston for a perfect match hydraulically. Listing is found here, and will email install guide if asked (tech at scarebird dot com). This will clear some 14" rims and all 15" we have seen.
We also have a budget set coming that will retain the SBP and require light work on the existing drum hubs and should clear the "A" 14" drum poverty wheels.
