Well, the search for this mystery vibration continues. The vibration is present with the pinion at it's factory setting, up and down 2* and I have additionally added another 1/4" of spacer to raise the output shaft on the trans.

I just got the car back from the exhaust shop and that is no longer hitting anywhere on the car, so that is also not the culprit.

I guess my next areas to look at are probably the torque converter and possibly the transmission itself.
