Many years ago my good friend and I replaced his 68 Dart front drums to disc. I'm not sure where he bought the brackets. I do know this much, they were aftermarket brackets. We took the drum stuff off and literally bolted the whole kit to his existing spindles. I have searched Dr Diff, right stuff etc and can't find an A body "stock knuckle to disc adapter". Am I not looking in the right spot? I've searched this sight over and over this mornin looking for that info.
 
It worked well and saved a bunch of hassle. It might have used GM calipers though. Uggh
 
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.

Well, I have 15" on it now. I'm 100% ready for big bolt swap too. I understand I'll have to deal with the rear axle at some point. Did you fab up your own caliper adapters? I'm good doing what you said if I don't have to spend 5 days on a press brake bending brackets. I've been there and done that.
 
I made my own adapters indeed.
Started out by using cardboard as a template, then switched to wood and later to a lasercut steel plate.
The adapters pictured here were made for a '64 spindle boltpattern;

Here are similar adapters for a '60 spindle boltpattern;

That's nice work. I'm more strapped for time than anything. I have a pretty good little fab shop at the house. It's just time consuming to make those things. Nice job by the way. Did you write the program and have a cutter burn em?
 
It can be a bit time consuming, but also rewarding when you end up with a improved brake system.
I entered the adapter measurements from the car into a graphics program and saved this as a dwg-file for the laser or watercutter.
