70 Swinger over center clutch spring

Yes. That spring is to help pressing the pedal in for a Borg and Beck 3 finger style clutch. Not to help hold the clutch pedal up. Most manufacturers of the diaphragm clutch ask you to remove the OC spring. A friend has never removed one from his show.car T/A's and AAR's, but he barely drives them. My Centerforce would stick to the floor without the engine running. The small spring from the fork to bellhousing is important to keep the throwout bearing from the fingers.
