Dual Control Car

I am currently working on a dual control 64 IV automatic and need a valve
that I can connect both master cylinders to that will allow fluid under
pressure to flow from one to the power booster while blocking the
pressurized fluid from backing up into the other master cylinder. Does
anybody know of such a valve readily available...perhaps in the aircraft
industry? Or will I have to fabricate one?
 Any ideas would be appreciated. If I can't find something I plan on making
the valve similiar to a "T" fitting, hooking each master cylinder to the
ends and the booster to the middle "T" with a double ended needle valve
(sort of like the one in a carburetor) that would slide end to end in the
"T" when pressurized from either side, sliding far enough to uncover the "T"
opening and sealing off the other end of the fitting.
Perhaps someone has a better idea. I guess I could use a hydraulic control
valve similar to a single pole double throw switch but that would have to be
manually operated . Your thoughts please?
