1972 Front Disc Brake Conversion

I actually got a sales guy on the phone who was rather bitter about leed brakes mimicking their kits. Brackets everything are the same. The kits use a spacer and adapter behind the inner bearing to move the rotor outboard to match to the caliper location. It also provides the larger diameter seat to use the Phord inner wheel seal.

Ah, ok. I thought there was something with the inner seal, that makes sense. I probably got that out of the Mustang KH rotor thread where people were doing the conversion themselves.

As a side note. Dynamic Friction makes new KH calipers for Mopar A bodies. You can use the Mopar caliper on those kits to retain the Mopar style brake line hardware. I plan on doing that with the kit for B body drum spindle since it uses the 73-76 A body lower ball joint.

KH disc brakes with BBP and no problems with rotor replacement etc.

So this I don't understand. If you're using the B-body spindle, you have to use the large upper ball joint UCA or an adapter. And you say you're switching to BBP as well. So, why mess with any of the conversion kit at all? Just use the stock '73+ A-body disks. Large ball joints, BBP, and larger wheel bearings too. Plus 100% off the shelf OE parts with no adapters needed for bearings or seals, and no hub issues at all because it's all integral with the rotor.
