High Speed Vibration - M6

High Speed Vibration - M6
Symptoms:
Vibration is present with clutch in or out
Vibration is present in or out of gear
Vibration is present at 65, goes away at 70, and is really bad at 75 and higher.
I can feel it in the floorboard, through the shifter, and in the clutch pedal.
Is this the driveshaft, trans, or clutch? With 4.10 gears I figure the driveshaft is a good guess. However I can feel it in the clutch so I don't know if that is it or not. Any help is appreciated.

I had it at 80 when I had 4.10 gears. Alum driveshaft helped ALOT, but there is still a slight twinge at 100 just cuz I know now what to feel. Some of our cars just have the problem, GM took a lot of heat over it. But over 100 mph there is so much going on I don't notice anymore.

I used to have a very similar issue with my car. I went thru everything from lca's to a cf driveshaft to a brand new tranny from gm (and a whole bunch in between). After all of that, i had lca relocators installed, the car drives smooth now. Make sure your geometry is correct, mainly pinion angle. If you have upgraded suspension, try lca rel. brackets. Good luck...
