74 dart vibration problem.

Had the trans pulled and the TQ spun and checked. TQ was 40 grams off so they added another weight right next to the one there already to zero it out. Only have vibration up to 2000 rpms and really not too bad. There's still a little vibration left and all we can see is that the main crank pully is a little bent and wobbles a little, but tight. Noy sure if that would cause the vibration though.
