What was the first year for the 465 trans? What was the last year? Were there ever any major changes done to it during the time it was used? Thanks, Kevin

other than shafts no, same deal

Are those the spline counts on the input or output shaft? Were the ratios ever changed from 68-91? Thanks for the info, Kevin
