66 Dart master cylinder replacement

I'm doing the exact same thing this week on my '66 Barracuda. Got a Napa NMC P1874M master cylinder and the distribution block from Year One.

Its my understanding that for manual drum brakes you don't need a prop valve, you only need the distribution block for a duel reservoir master cylinder car.

The distribution block from year one was 39 bucks. Here's the link: https://www.yearone.com/Product/DisplayProduct/226822

It seems to be high quality and bolts right in the stock location so I should be able to reuse the old brake lines since they were all replaced about 3 years ago. I'll let ya know how it all works out!
