Interesting-the tech who worked on the car mentioned wanting to check that when he did his test drive. I guess it was good. The remaining vibration is speed sensitive and feels rotational. That said, however, I'm going to ask if that inspection was actually done.
After thinking it through a bit more carefully, I believe whatever was the original source of vibration is still there but because the drive-line "anchorage" has been tightened and strengthened, the manner in which the vibration is now experienced has changed. Just for "shitz and giggles" do you know where I can buy the bushing (s) ? Thanks!
