70 Swinger over center clutch spring

The OC spring is there to help bring the clutch pedal back up off the floor when your shift is done. It does not assist with pushing the clutch to the floor. I think that's what you were saying. I may have mis-read the question.
Press clutch pedal down, the spring is extended. Let off the clutch pedal and the spring resistance pulls the pedal back to it's resting spot.
