Proportioning valve or no for 65 Dart disc/drum brake conversion.

Finally getting around to converting to front disc on my 273 hipo 4-speed 65. Car currently has 10” drums and 14” rallyes. I was thinking about going Pirate Jack for manual disc brakes. I have already converted to dual master and have the new disc brake compatible master. I’m guessing I don’t need a proportioning valve. Am I wrong?

Also, I think this kit doesn’t need new ball joints and the current 14” OEM later A rallyes will fit.

Good kit or is there a better kit that isn’t overkill?
