Well this weekend I was out in my 93 mustang and for some reason it didn't want to go into gear. I adjusted the adjustable quadrant I have further, thinking maybe the clutch cable stretched, and the shifting problem isn't as bad getting it into gear, but when I drive the shifter vibrates horribly when the car is in gear. The car still gets up and goes fine, so I think the clutch is fine, but Im curious about the vibration. Could it be the throwout bearing? I really have no clue, so please give me some ideas.....
 
It doesn't shake at all in neutral or while I'm rolling. And it shakes in all gears. It still doesn't like to shift into gears as smooth as it should, but it does go into gear ( i have a pro 50 short throw if it matters) And the more rpm the car spins, the more the shifter vibrates
 
Thanks a lot for the suggestions. I'm gonna get under there this afternoon and try to find the culprit. Maybe a lose driveshaft bolt or something that's an easy fix.
 
Be sure that all the driveshaft balance weights are still there. They are spot welded on, and one of them could have come of from the shock of a really hard shift or burnout.
