Nick, I got the hub turned and squared up and most of the shake went away. I did some more reading and checked into a few things and did some analysis (Ichikawa diagram) on when the shake started and what had been done in that immediate time frame. New tranny, with spacers to raise the clutch cylinder off of the frame. (More spacer than was really needed.) Working backwards, I removed the spacer under the cross member and changed the angle between the drive shaft and the differential about 1/2 degree and guess what? No More Shake. I find that amazing. In any event, it's solved. Took the car on the Route 66 Fun Run this weekend and put almost 1000 miles on in three days. No shake anywhere up to 105 MPH. I think I'm set. Thanks everyone for your help with this. I really appreciate everyone's input.
