Only difference may be the pinion flange. If the 70 diff came from a 4 speed car you will have to change the flange or get a conversion u-joint.

The 63-64 posi unit, ring and pinion, etc. are different. The 63-64 is a Dana unit, while 65-79's use an Eaton. There are very few parts available for a 63-64 rear, but they can be updated by installing 65 up components in them.

If need be, he should be able to reuse the front flange, from his existing rear.

Sorry to hijack the thread, but one more question. Is one stronger than the other?

The 63-64 Dana unit is very weak. Odds are it has already been changed out with an eaton unit.

So if mine has held up behind a zz502 for the last 2 years, it's safe to assume that it's been changed out?

There's no way the Dana unit could handle a 502.
