Axle ratio question
Hello all I recently purchased a 1970 gto with the original M21 trans, the previous owner said the axle ratio was 3:55 from what I have been reading the car would have been equipped with a 3:90 rear end. I know its not a 4:33 from driving it, what are the chances that it is a 3:55 ratio, the axle code is no longer visible on the tube after 40+ years of rust and paint. Thanks for the help.
