Since we are doing it all over I decided to ditch the old single fruit jar style master cylinder in favor of a much safer 67 / 70 Ford Mustang OE unit (C9AZ-2140-D) for manual drum brakes ( Group # 10-1485 ). I picked this particular unit because it has the outlets on the driver side away from the engine. This unit also has a great feature of having a 10# residual valves built in. The cool part is that this dual master cylinder was a straight bolt-in! The plumbing is not that complicated and I installed an early pressure style stop light switch ( BWD Part No. S194P ) that is plumbed into one of the feed lines. I am leaving the stock distribution block in place but I am just capping off the outlet that would normally feed the rear brakes. That hooks right in to the new master cylinder.
With the new fuel pump having an integrated fuel filter the fuel line plumbing will be pretty simple. Out of the fuel pump and heading back along the frame to the tank at the back. The downside is that this will have to be massaged and fitted to the frame and crossovers. Not a big deal just tedious.
