If you're planning to do the disc brake swap at some point but want to do the dual-circuit master cylinder upgrade NOW, but the cheapest '67 manual brake master cylinder you can find, run the front brake line to the existing distribution block and put a plug into the rear circuit port in the block, and run the rear line directly to the rear line directly to the master.
You're not going to find a practical solution to upgrading the master to one that will function properly with both 4-wheel drum and disc/drum systems. Either do the disc brake and master upgrades at the same time or spend the extra fifty bucks.
What, me worry?
