    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 :k5:

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

    1980-1984 one ton trucks with a NP205 and SM465 remained ten spline until '85.

    Go to the 4-wheel offroad website and look in the chevy section . They have a whole writeup on it.
