1965 Valiant brake woes

So, if I've replaced two bad front drums and some bad wheels cylinders, I should have everything at the wheels ready to go.

My plan now is the Raybestos dual circuit master cylinder, as used on '68- drum/drum cars, and adjustable pushrod, and the distribution block. This should get me back as close as possible to factory 10" drum/drum brakes, like on later model Darts, etc.
Sound like a solid approach?
