Disc brake conversion (70 Dart)

Hello all;
This is the first time I've written anything on FABO, so bear with me and my ignorance.
Regarding the 70 Dart disc break conversion.
I'm sure this has crossed the forum before, but here it goes....
I used 73-76 A body V8 disc break spindles with 78-80 Chrysler Cordoba adapter, calibers, and rotors on my 70 Dart, they work great.
You do need to get larger wheels though.
I'm sure you need to change the proportioning valve to something else, but I didn't and they seem to work.
There over the counter parts and somewhat inexpensive.
Please tell me if I'm full of it or if this modification works.
Again, this is my first time submitting anything on FABO.
Thanks for reading and any support is well appreciated.

Yup, that modification works great. Those are 11.75" rotors with the same 2.75" piston diameter Mopar calipers. They'll outperform the 10.95" rotors for braking force because of the larger diameter rotor, and they make for a great braking system.

They do require 15" rims though, and like the 10.95", 73+ rotors they're the large bolt pattern.

If you have the 73+ spindles, all you need to use the 11.75" rotors is the rotors themselves and a new set of caliper brackets. DoctorDiff sells them new if you can't find them locally.
