I have an 87 gt with a Tremec transmission and i have a bad vibration. the vibration is there still with the clutch in, in neutral, not moving, and rev it up. does anybody have any ideas? thanks

Does the whole car vibrate? Could be the clutch?

yeah the whole car does do you think it would be the clutch or transmission

Bad harmonic balancer? wrong flywheel? are you sure it's not just a misfire?

the whole car shakes and vibrates when you rev it past 2.

+1 on the "2 piece harmonic balancer" I had the same problem!
If its spun its to hard to tell but she shakes look out!!!!!!!!!!!
Does it make and noise?

no noise, just a bad shake, engine runs smooth. somebody told me the problem could be with my clutch, throwout bearing, or the shaft coming out of the transmission.

^Not very likely related to the clutch, t/bearing or input shaft. It's probably a bad balancer or wrong flywheel/unbalanced flywheel.

Actually tremecs sometimes have a problem with too much end play on the input shaft if you call there tech line they will send you a kit and tell you how to measure the end play and what the spec is . This sometimes leads to vibration!
