I think you're right about the mech not marking the orientation on the
drive shaft. It *does* sound like it might be a balance problem. The shims
are just for alignment up and down, the tangs are slotted for alignment
right to left. I *just* happen to have a known good drive shaft out and on
the floor - you might want to drive up here and take a peek and some
measurements.

There's also a guy here in town "Gary's Drive Line", who works on jacked-up
redneck pickup trucks. I spoke with him once about the Q driveshaft, and he
said he'd be glad to look at it. He has a good reputation here about
solving driveshaft problems. I had the same problem as you; the guy who
took it apart never bothered to mark alignment, and he also lost some bits,
so I bought a replacement shaft from Chris Semple.
