Okay, now the clutch is fine. It turns out the SPEC throw-out bearing was the problem. The problem I have now is a BAD vibration at 1800RPM and above. Doesn't matter what gear I'm in or if the clutch is engaged or disengaged. The car is also vibrating alot more at idle than it used to. Again the clutch doesn't matter. The only other things I did to the car at the same time was: 1) Replaced the stock tranny mount with a urethane mount. Will the urethane mount transmit more vibrations from the tranny than the stock one did? 2) Put in an aluminum driveshaft from Ford Motorsports. I did have to use the stock yoke though. Could it now be out of balance? Any thoughts/help on this would be greatly appreciated. Thanks.
