Disc brake conversion (70 Dart)

Any disc brake setup is an upgrade over drums. Still, 1000’s are still stopping on drums with much success, myself included! It’s worth doing the swap, and if you can afford it, and want to go that way, buy aftermarket. Me, I can do well with factory parts just fine, and would use the factory setup if I had it around and it was in decent shape. For 90% of the cars out there, it’s just fine!
