Pedal rod to Z bar question.

I had issues like that on my 66 Dart. The replacement clutch worked good but the pedal didn't return to the stop. After properly adjusting the clutch, I just got a hardware store spring and added it to the petal. I stress this because I feel it's very important: Remove your inspection cover and adjust the clutch by the gap between the throw out bearing and pressure plate fingers. They shouldn't touch. I adjust with a 1/8-3/16" gap. I ruined a clutch by adjusting it by the pedal travel only. The t/o bearing was riding on the PP fingers, it smoked the bearing and ate the tips of the fingers.
