Duster Front Drum/Disk Conversion Questions

If it were my car. I'd just with a 73-up style disc brake set up and be done with it. Perfect for what you are doing. No need for power brakes either. Call dr. Diff a call. He will have what you need.

I agree. Unless your stuck on keeping the small bolt pattern.
FMJ/late B discs work too and much more likely to find them.
Pretty simple stuff.
