Just took this out of 67 GT350 #2246. Bracket was '71 dated service part, but no idea when it was actually installed. They welded in a large diameter piece of tube and went grinding on the brake pedal until everything lined up right. Put the brake pedal dead on with the gas. Worked fine but just couldn't get used to the brake pedal starting so low, so I have an original pedal set I'm cleaning up and putting in.
Picture of original set added just for quick comparison.
