Drum spindle adapter to disc?

If you're creative you can come up with your own discbrake adapters and use all Mopar parts.

I fabbed discs on drumspindles on 2 of my early '60s Chryslers. Using stock '73 C-body rotors, calipers and B-body adapters, it's all Mopar.
Only down/upside is you have to switch to 15" wheels because of the larger 11,75" rotor.
