While an original drum/drum mc will work for your scenario, it is not necessarily the correct approach, even with an adjustable disk/drum prop valve. There is a difference between drum/drum and disk/drum mc’s. It’s worth spending the $25-30-ish bucks for a correctly matched system. It’s not the fact that you’re converting to hydroboost - it’s because you’re converting from drum/drum that drives the need for a correct mc. (In other words, if you were converting a 71 or newer to hydroboost, no you would not necessarily need a new mc).
