Can't you run a bulkhead type twin circuit under floor or behind dash ( using 90' bellcrank ) ? Remote servos create issues for space etc ,and if higher than m/c bleeding /bleedback probs as well . Plus OEM haven't used single circuit brakes in about 50 yeras ;)

No , I meant twin master cylinder WITH servo . Instead of facing out towards the radiator you put it facing towards the passenger side and then use an intermediate lever ( bell crank) to transfer the push pedal movement to across thecar instead.

Ok, try to picture this ,90' bracket to right of brake pedal ,back edge runs parallel to bulkhead then it's pivot and the bar then points towards you. Push on brake pedal , rod pushes forward ,bar at bulkhead moves back , angled pice towards you moves across car ,at 90' pushing servo rod :)

Easiest way to get bellcrank, bushes etc is look at stuff like Golfs , Polos, and Escorts with the servo mounted on the left hand side of engine bay ,they have rod across bulkhead with bellcranks.

Depends on your braking requirements, I got one under the dash of a 23T :) Also you can use it under floor but near the back with rose joint supports on the rod .

Coupl eof servo /mc combos mount upright even. Depends what bore you need for your axle brakes.
