Disc brake conversion recommendations

Just wondering who's using what to convert from front drum to power disc. Good experience? bad experience? 2 inch drop spindles? Or should I just find the factory stuff and maybe use a dual power booster just to save some room under the hood? This is for a 69 Dart
I have a 70 Dart and am planning on doing a front disc upgrade in the spring. I too live in Cleveland. Maybe we share notes on this project. I want to keep my 14 inch sbp wheels for the stock look.
