Front disc brake conversion question

I am putting bbp disc brakes from a 1974 dart to my 1972 340 demon that came with manual drum brakes. What power brake booster and master cylinder with prop valve would work best for me? I hate to rehash this but I have read countless threads and I have not seen a good straight answer. Please help me before I give up and put my drums back on. Thanks Ken
Use all the system parts from the '74 Dart- booster, offset bracket, master and prop. valve. Heck, grab the master to prop valve lines too while you're at it.
