The '49-'51 Fords use a unique master cylinder that also supports the clutch linkage, so there is no direct dual master cylinder replacement. (Well, the '67 Ford Econoline dual master, a one-year-only part,
may work if you could find one.)
The common dual master upgrade places the new dual master behind the original on a custom bracket that bolts to the frame. The original master
can be gutted to allow a longer push rod in the original location, or offset the new push rod along side the original master, like I did on my '51.
I'm using a 1" disc/drum master with 10 lb. inline residuals with the stock drum brakes. The present master will make it easier when I finally upgrade the fronts to discs, with just a front residual change from 10 to 2 lbs.
