63 Dart front disc m/cyl?

Thanks for the advice, Just to confirm, the M/Cyl was from the 73/6 Dart? and did you use or need a proportioning valve?

I have put 1980 Aspen disc brakes to my 1964 Dart and used Dart 1973-76 model upper control arms and manual (not power) master brake cylinder. Combo works just fine. (See my photo gallery.)
