Clutch Pedal Not Returning

Agreed. At this point of lack of information, who knows if the under-dash spring is even in the car? Checking the pedal travel comes AFTER knowing what you're working with in the first place.

Curious that it's not even said if the installed clutch is for a chevy (diaphragm). I vote for B&B pressure plates being used for a reason. B/B-Long combo even!

If you can't handle a B&B plate, buy an escort, or put in a 727.

My 5'3" 105lb wife drove our '68 Charger 440 833 (B&B plate) just fine. I'm sure you can drive one.
