Best disk brake kit for 65 Dart?

What went wrong? I don't have any personal experience, but a couple friends have used them on an A100 and a Sweptline.
I had my hubs re-drilled for the 5 on 4-1/2 bolt pattern. The wheels with the bigger bolt pattern have a larger center hole. I tried using hub centric rings, but that didn't work very well. I still have all that stuff if someone wants it. $100. plus the ride and its yours.
