Replace the mount. They can be a source of vibration especially the drivers
side mount. Is the vibration in the steering wheel or seat of your pants?
Does it still vibrate when you are in neutral? Does it happen at the same
rpm in each gear? This will help diagnose the source of the problem. You
could just have an unbalanced tire...

I have a vibration problem in my '80 B.It occurs mostly when shifting
or at higher speeds when I let off of the gas at higher speeds.(55-65mph)
I've had the car on a lift and the exhaust system is solid.The clutch was
replaced about a year ago. I checked the motor mounts and the left front
has a crack ,but I cannot see any movement there when I rev the engine.
Your diagnosis of probable cause would be greatly appreciated.
