I have a question for you on the vibration. Did you have any work done to it right before it started? Besides the clutch? I would check the belt drive line be sure its all straight. Is motor rebuilt? The crank and fly wheel may be out of balance, and yes the clutch may have shifted the material which will cause the vibration. My contour had that vibration going and once I swaped tranny's I noticed the material was pulling off the clutch plate. When done all was good. No more vib's. Oh and Nice Stang man!! Love em!
