Just changed out the motor and tranny mounts on my 89GT and wow what a improvment. Now more difficult shifts, vibration, shifter shake, clunking, and it now the whole car doesnt shake like it has the worlds biggest cam in it. Have'nttaken it on the highwau yet but i hope its alot smoother. I do still have a little vibration @ 3500 when in neutral but it clears up after 4k. i guess the harmonic balancer is next in order, along with a new rack and offset bushings.
