I used a kit from Fat Mans for a Mustang II master cylinder on my '49. It bolts right to the frame where the original was an uses the original pedal. Just one thing. The rod going from the pedal to the MC is adjustable. You will probably have to adjust it a little to get proper braking action. Voice of experience!
