Power brake booster
The rod that goes into the vacuum booster is part of the bracket. It attaches to a lever on the bracket, not to your pedal. The flat bar to the pedal is also part of the bracket. Since you are getting all together, they all fit. The only question is if your pedal would be in the correct place. Should be, since I don't think the brake pedal bracket changed from 71 to 75. My 65 is different, but my brake pedal seems to sit in the correct place, and I was able to adjust the pedal switch fine.
