So I am switching from Auto to Manual in my 70 'Cuda and I just installed a new clutch spring and it appears to do very little. It certainly does not keep the pedal up.

I have three theories but no experience to know which is more likely; 1) This spring is damaged and not as tight as it should be or 2) The spring doesn't hold the pedal up and doesn't really do much. 3) I don't have the spring installed correctly.

Any ideas?
