If you are going to use your old single outlet master, no valve is meeded. Dual master cylinders can be plumbed for cross or front/rear braking. Either way, no valve for all drums.

If you get the master cylinder for a drum/drum setup you don't need a proportioning valve or cross-plumbing. My 69 has drum/drum power brakes with a dual master cylinder.

Tell him to think about www.praisedyno.com for some shoes. That, with power, should make his braking very nice (on par with factory disc).

You're right about the single resevoirs only to '66. I was thinking about my panel when I wrote that, which I changed to dual with drums, then put 78 x-member in, with prop valve.
