If you haven't gotten a dual MC yet (didn't read all 30 pages), in my 1964 Valiant w/ manual brakes, I used an MC for a 1998 Breeze/Status w/ ABS (2 ports) on a 4-2 bolt adapter plate ($30 ebay). The pedal rod locked into the MC piston w/ a new rubber bushing and the pedal wound up in the same place. Search for my post. Many other options, like the 1980's Dodge truck MC. Dr Diff sells a kit w/ essentially that.
