---Couldn't find anything through AC-Delco. I don't know if it would work,
but have you asked about a master cylinder for the `74 Scout II with front
drums? That would give you equal capacity reservoirs and maybe even a
combination valve.

-`73 Scout II (StoneThrower)
-`51 Farmall H (Heinz)
-`49 IH fridge (presently unnamed and in need of a compressor)
-`49 Plymouth Special Deluxe 4-door Sedan (Papapalooza)
