Power disc to manual disc.

1968 Form. S. fish with power frt disc brakes. I want to take the pwr booster off and just go manual disc. The Paddock shows the same part # for pwr disc master cyl. as for the non pwr disc master cyl. Year one 's part # is slightly different. Anybody done this? I would think this means that possibly I could just pull off the booster and install manual disc pedal to master cyl. rod and same master cyl. and be done? Thoughts on this are greatly appreciated.
