My '67 Barracuda which I have owned for 42 years finally got dug back out of the barn. After a whole bunch of part replacing, I am now down to factory power brakes that appear to have lost the booster. I would guess after all these years internals are shot. I think this is the 7-1/2" variant and it has the 4- bolt pattern on both ends. Does anyone make these for replacement? Mine is not pretty anymore as the Cad is all worn off. I have searched lots of places and nothing so far. Master cylinder is new and I would rather stay with a factory style if possible. Anyone know?
