Major Vibration Issues - Help

Yeah not sure it's clutch/Pressure-plate. It's not rpm dependent. It's more speed related. Clutch pressed in or out if I rev up to 4000 rpm parked there are no vibes. When they installed the clutch could they have thrown something loose in the drive shaft or u joint somehow?

I took a video underneath the car of the rear drive shaft, next to the rear wheels, so that you can all see where the vibrating problem could be originating from. I have the car up on jack stands and I take it up to 80km/hr where it starts to get really bad. Notice the noise it makes as it slows down near the end as well.

Any thoughts? After the clutch kit was recently installed could the problem be because my mechanic didn't aligned the drive shaft properly? Propeller shaft run out tolerances?

By visual inspection the drive shaft appears to have all of the nuts and bolts tightened down effectively. I guess I'll need to take it to the Nissan dealer to have the drive shaft serviced...
