Well, I think I figured it out: why the over drive would not engage for the first couple of miles: low voltage. I still have a generator, the original probably, think the voltage is too low. The 30 amp number for engagement sticks in my mind. Seem like the engine runs better with higher voltage also. Not surprised, this was a seriously used vehicle and probably just limped along in the last days of it's previous life.

When I wind the revs up to get past 60 in 4th, THEN the o-drive engages without an issue, and is generally ok for the rest of the days tour. Only after it cools does it falter again.

I found an alternator bracket in the wet bucket of parts I got with the car, so I'm ready for that change.

Which orientation is best ? 12 3 or 6?
10SI, 63 amp, at 3:00 (AC-DELCO # 321-39)
10SI, 63 amp 9:00 orientation (AC-DELCO # 321-41)
10SI, 63 amp 12:00 orientation (AC-DELCO # 321-43)

And thanks again to PhilS and RonK for the instruction pages:
