Need help identifying the year of this master cylinder/brake booster
Close. It's actually a '73-'7
5 A-body unit. The '76 boosters are different.
Make sure to get a
new master cylinder from a reputable brand (Bendix or Raybestos); "remanufactured" ones are garbage. As for the booster, the only ones available through parts store are (again) "remanufactured" junk. Use
Booster Dewey instead.
