so I took out the other driveshaft that was in the car, lined it up with my "mis-matched" one, that I had forgotten to mark prior to disassembly, and lo and behold, it became apparent how they should be lined up. Both of these were vintage 74, so that may have helped, but the four bolt holes on either end are offset 45 degrees frmo each end, (or is it 90) any way they do not line up if you were to slide a long bolt thru on end down to the other.

Then the counter weights solved the issue on the four possiblities remaining.

Put together, bolted up into the car, off some hot laps down the freeway, not vibration no squeaks, should be good to go .
