Disc Converstion Help 71 Swinger

Hi everyone,I have done a drum to disc conversion on my 1968 Dart.I used the parts off a 1976 Dart.I cant remember if the 1976 Dart had power or manual brakes and dont have axcess to the car anymore. I want to stay with the manual brakes for now,my question is..what master cylinder do I order? Manual or power.The listing my jobber has is power with disc or manual with drum??????? Thanks .
