69 Dart 340/727, currently with power brakes, 10" drums all around. Everything is getting replaced, with a new 8-3/4 rear end and 11x2 drums on the back, and a full front end rebuild with the 73+ disc brake upgrade in front. All the lines will be replaced. I don't have any craving for power brakes and the engine compartment would be cleaner and easier to work in with manual brakes. Other than neeeding a disc/drum master cylinder and adjustable prop valve, is there anything else to know about making this swap? I wondered if the push rod for the master is the same or ??

I'd like to gather all the parts before I start taking things apart, you help is appreciated!

I’m not sure you need an adjustable prop valve. I have a 73 and I took the power brakes off because they are big, nasty master cylinders and boosters. And I like the feel of manual brakes much better. It’s just a cleaner look.

I bought the MC and pushrod from in-line tube. Pretty much a bolt in deal.
 
I think you will want the adjustable prop valve, because you are putting much larger drums in back than the factory did, so the master will wind up rear-biased. If the rears lock up before the fronts, you might as well have kept the drums in front. BTDT.
