Hello, newbie to the forum. looking for advice. Bought a 64 /14 mustang and trying to get it to a reasonable condition. (it runs). It has a single bowl master cylinder with a brake booster. Can this be upgraded to a dual bowl with the existing booster? Not sure if there is enough room. Also not sure what the spec is on the booster. The car has drum brakes all round. Thanks in advance for any advice. Attached are pics of what I have.
