Weird Vibration!

Had the same problem with my cuda a while back. Replaced the 4 spd with a 727 and had the drive shaft cut. That was the problem, it was indexed wrong and slightly out of balance. Took it to a machine shop and 100 bucks later it's perfect...no vibration.

What did you take to the machine shop?

I crawld under the car, and grabed the drive shaft and shook it. There is some play where the yoke slips into the tranny. What bearing or bushing is there? and is it easy to change?
