Exactly...

True, but the car needs the correct stance, a slight rake from the back to the front, and not 4x4 tire clearance.

Well my car is lowered by 2" all around with a nice looking stance. It has a very slight rake, same as before using a level between the wheel wells. Used reverse eye grab a traks and cut one full coil from the fronts. Time to drive and settle out, then re-measure the angles.

OK had the same issue with a 33 Ford Vicky ..chased the vibration for months. I bought the car and it always had it at 70 mph and grew. OK did everything then I decided to adjust the four link (TCI Chassis w/triangulated four link and 9" rear) Man they were tight! Finally got them to move. I decided to mark them and then move it a bunch so I could tell if it made any difference. It cured the problem! This car was build over 10 years ago and they never got the vibration to go away. Well now No vibration at any speed like 95 plus and smooth!!!! So my suggestion try it.

The issue was due to a worn slip yoke and that would quickly wear on the new tail shaft bushing. Replacing both items at the same time solved the problem its been solid for the last 7 years.

I do want to go with the TCP 4 link though.
