I got the car back from the driveline shop yesterday. While there, I ran it on a lift to 3000 rpm in neutral and all gears with old universal yoke in place of the drive shaft. The engine/trans ran smoothly except for 5th or overdrive. It has a strong vibration in like what I'm feeling on the road. So I think there is some play in the overdrive portion of the trans.
When I drove it home it seemed smoother than before, so the driveshaft angle correction helped somewhat with vibration at about 65 mph in overdrive. But, I plan to have the trans rebuilt to correct the overdrive vibration.
Thanks for your help.
