Default Clutch vibration

What is the best way to check for it to make sure it is in the clutch and not the trans or rear end.
I just finished building a 408 i reused the old clutch from the LS1 it was a SPEC 3 it did not vibrate before. I'm just wodering if something may have caused it to become unbalanced.
I also added poly engine and trans mounts. The vibration does not feel speed related as much as it does rpm wise. It seem to vibrate @ 3,000 and up. Thanks for any HELP!!!!!!!!

If it vibrates when the car isn't moving while you are reving it, then the problem is in front of the transmission. If it revs smooth but vibrates going down the road, it's behind the pressure plate.

This is true. Right now my car vibrates in neutral pretty bad. We decided it was the clutch & now I'm saving for a LS7 w/LS2 flywheel.
