This is a good point, I kept breaking trans tailshafts only to find out my DS wasnt balanced

I had the same issue sort of but it was the driveshaft was rotated 180 degrees out and it would vibrate like motherfucker over 3-4k rpms

One thing to think about...
Are you sure it's not a vibrationbehind the motor?

I got a converter from my transmission sponsor(a while back) and put it behind a new
motor build(LS1 zero balance).
I thought the shake was in the motor, but it was the converter.
Isolated the issue by pulling back the tranny and converter, then rev'ed up the motor.
Motor was solid.

It turned out the converter was setup for my specs for stall and STR, but not
zero-balanced. I suppose a little extra weld bead on one side made the difference.

Check to see if you may have lost any balance weights in the drive train.

I've seen a balancer half way off, saw one that was separating, and I've seen drive
shafts with bad u-joints, and lost balance weights, lost bolts. I've seen balance flex
plates put on zero-balance motors, etc.

Get some eyes on everything and work to isolate the component that has the issue.

I'm on vacation next week so going to try to get the tranny backed off and see if it smooths out

Surely you were going to already, but be sure to rev the motor a bit after you pull the driveshaft. No sense in pulling the tranny if it happens to be the shaft that's out of balance.

Why not just press the clutch with trans is gear to eliminate driveline issues without pulling anything?

The only thing you can't test with it all together is the pressure plate balance.

This was my thinking but people insist somethings are still turning even when clutch depressed

If the clutch is in, engine running and car is stopped(e-brake up), the driveshaft sure as shit isnt spinning.
