hello, im working on getting brakes on my project car. the car is a 74 dart with power disc brakes . it came to me without a master cyl or booster, only the mount that is attached to the pedal. the mount looks like a new one. i bought a booster to fit a 74 but the holes in the mount are slightly narrower than the studs in the booster. could someone look at the mount to see if it looks like the original or is it for some other booster. thanks
