I just put a Steeda Quad, Cable, and FWA on my 91 GT today. Before this install, there was no vibration in the clutch, it caught at about halfway up the pedal, and there was no free play at the top of the pedal. Now there is about 1.5"-2" free play at the top, it catches at about 1/2" from the floor, and it vibrates when the clutch is disengaged (pedal released). I cannot figure out how to adjust the firewall adjuster, because nothing i do seems to make a difference. Any help or ideas on this would be greatly appreciated!
