The '65 to early '70 12 bolts are exactly the same, as in a direct swap. The '63-'64 12 bolt will bolt up except they are setup for the long panhard bar. The long panhard bar can work with a slight bend in the frame end.
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.

Hey Captain did we confirm that a 1967--early 1970 with 6 lug axles is the correct one? Oh and do you know if the v8 auto's had a tall gear?
thanks
