I have been driving my 66 mustang for 4 months now as a DD and the vibe is starting to bother me. When I first got it there were a lot of things I fixed that I would have thought fixed it, but I still have the vibes.
-I replaced the harmonic balancer, the original one was spun and just toast
-I checked the flywheel to make sure it was 28oz
-It had a newer clutch/pressure plate, but the throwout bearing was toast, so I changed that
-The drivers side motor mount was separated and the motor was laying on the header, fixed that and nothing
-Replaced the rear ujoints, this fixed my driveline vibration, but still have the motor vibration.
Vibes are worst at 3,000 rpms. It seems like the whole car shakes, and its worst through the shifter. When I'm driving on the E-way it feels like the vibes are pulsating also.
