I have a 1956 T- Bird and would like to change over original master cylinder to a dual unit. I already have installed disc brakes on the front and have original drums on the rear. I have been told that an early seventies non power type mustang will bolt up and will work but I need the part number and year. Also part number for the proportioning valve. Does someone have this current setup that can give me some numbers and possibly a photo or two of their setup. I know a couple of suppliers sell complete kits but they will not sell individual components from those kits. Thanks
