Ok so what is the differance between 1st,2nd, and 3rd gear bushings for a 1972 year and old years transmission? Ppl I ordered my bushings from said the 1st and 2nd gears bushings are the same, but the 3rd gear bushing isnt and apparently the 3rd gear bushing on the later years model trans is different then the early model. Can someone enlighten me on what the differance is. Cuz I apparently got the wrong 3rd gear bushing if this is true because all my bushings seem to be the exact same size.

Thanks,
Mike
