'67 Barracuda Fastback S 383 4 speed rear end issue?

drawing shows there are renewable bushings. Finding new could be a challenge. No guessing if they are all the same size. The bushings at brake pedal weren't. Good luck
There is a FABO member that makes Replacement bronze bushings for the pedal assemblies. I put a set in mine, a year ago, they are nice pieces.
I will try to find his name,,,,
