Do you still have the stock adjuster? or did you or someone else put in an adjustable clutch quadrant and firewall adjuster?
My clutch got like that when I loosened the firewall adjuster trying to get the clutch to grab down low. There is lots of play in the pedal and when I went too far the car wouldnt go into gear well.. Too tight and I started slipping it bad at the track.
If it is the stock set up then you probably broke a tooth on the cheap plastic adjuster. I would put in the adjustable one.
