The master cylinder on the 47 Plymouth does mount the brake pedal. Some of the 12 Port News advertisers sleeve the master cylinders. This makes an acceptable reconditioned master cylinder. I am still running the double leading shoe drum brakes on my 48 Plymouth coupe, but will update to discs and a dual master cylinder some day. If you haven't driven a vehicle with drum brakes for a few years you tend to forget just how poorly they operate compared to a disc set up.
