Are you a 4x4 or 2wd? I can only speak of the 4x4.
In 4x4 trucks, GM made up the difference in drivetrain length with the transfercase adapter. The Sm465 is much longer than a Saginaw, therefore has a shorter adapter. The transfer case and crossmember are in the exact same place. GM did this so they could use the same drive shafts on 3 speed and 4 speed trucks.
In a 2wd, I would have to assume the tailshaft would be the difference. If the total legnth of the transmission is the same, and the yoke is also the same type you should be OK. I would put money on the Sm465 being longer overall, in which case you would have to shorten your drive shaft. Shortening of a drive shaft is usually pretty inexpensive at a shop and can be done at home if you have a chopsaw and a welder.
