1960 Valiant front disc brake conversion help needed

Unless I find out there are variants of wheel hubs for 9" brake drums, the next thing I'm going to need to figure out is if the dual master cylinder I bought is going to work or I need to get a different one, and what I need to do for proportioning valve. There is a 1974 Valiant in the local u-pick which I was figuring I'd grab the distribution block/proportioning valve or whatever if I'm able today.

Along with that, I've read that my single master cylinder pedal may not work properly with the dual master cylinder setup... Should I be grabbing the pedal from this 1974 Valiant as well perhaps? I may just grab everything anyway since the price is right.
