Michael,

I think they are different, from what I have read. Not sure of all the differences, however, one is the input pilot bearing retainer on a SM465 transmission is a larger diameter, therefor, the opening on bell housing is larger, then earlier ones, it is 5.125" diameter.
From previous post by CaptainFab, '68 to '72 trucks..... have the cast iron bell housing for the SM465 transmission. After '72, the bell housing were made of aluminum.
