On my 69 Mach, I converted from auto to manual trans. I don't see any location holes for the clutch fork return spring anywhere on the car, I can just drill a hole and locate the spring to the frame rail, but shouldn't there be one already there? or does the one end of spring attach to something other? I have the proper upper return spring for the Z-bar, when I push in the clutch pedal, it feels VERY light and barely returns, and can't figure out why. I would think a Centerforce pressure plate would have heavy pedal pressure but doesn't, whats the deal here? I can depress the clutch pedal by hand it is so light..humm?
All I can think of is the parts houses version (repo)of the return spring is lighter than stock, as the upper pedal spring under the dash is original

Hmmm, don't know if I can help much here. the fork return spring on my 68 hooks up to a hole in the equalizer bar (z-bar). As far as your being able to move the clutch pedal by hand, you got me. Mine is so damn tight it would make my leg sore when I had to drive in heavy "stop and go" traffic (used to live outside DC).

I have a 70 mach, it has a return spring on the z-bar. As far as the spring under the dash i believe this is an assist spring to make the pedal effort less. I have a Centerforce clutch in my car and because it is a diaphram pressure plate instead of a borg and beck it will has less effort. I remember in the box of the pressure plate it stated in BOLD PRINT to remove the assist spring under the dash or the pedal will stick to the floor at high rpms. Check the instruction sheet that came with it.

I have got the same situation I have so far put a heavier spring from the firewall to the z bar that helped quite a bit.
