Horrible Vibration issues going to kill myself.

I cant figure this out at all...

My car has bad vibration in all gears after 3K rpms.... you can feel the vibrations in the shifter above 70 mph. I have no idea what to pin point. I have an aluminum drive shaft, 6 month old 4:10's, Spohn TA, and the LCA brackets... the pinion angle is set at -2 degrees and it has seemed to increase vibrations. But it's killing me trying to figure out if it's the gears or what... The worse part is it's killing my HP. It feels like I'm going no were once I get above 3K rpms... anybody know what I might want to do.

The problem is defnantly between the gears and the drive shaft....
I've noticed the vibrations got worse the more - I made the pinion angle.

But the reason I'm curious is becasue at first it was just a small vibration... then it just kept getting worse till where it's at today.
It's a soft vibration at lower rpms, but the faster you spin the worse it gets.

I'm trying to give you a background on the issue.

I just pulled the transmission 2 days ago.

What brand Driveshaft is it, and how many RPMs was it balanced to. Not sure how tall/short of a tire you're running, but with 4.10s you're spinning a driveshaft a cosiderable amount of Rpms so it's good to have one well balanced.
