If you are just talking about the internal parts, all truck 12 bolt parts from '63-'82 will interchange. The one thing that is different is in the '63 and '64 12 bolts, they used 17 spline axles and spider gears. '64 and up used 30 spline.
The auto trans trucks could have 3.73's, 3.42's or 3.07's. Some of the later models came with 2.73's.

nice find Rocknrod!
I'm dropping a 383 stroker into my Mudhoney, and am worried about the ability of the drivetrain to handle the torque...
and this tidbit of information: "all truck 12 bolt parts from '63-'82 will interchange"
is pure gold!
