I know the answer is probably here in the thousands of pages but

I just put on a disk brake conversion kit on my '66 Dart. It was a Wilwood for the original 9" front brake setup. Going with the 5 x 4.5" setup and in the process of getting a 8.75 rear end to complement the back 5 x 4.5" and some more beef (probably go with 3.23's).
