'71 Clutch Pedal Return Spring Specs (#3921656)

[Ray K.]

Looking for spec help on the '71s clutch pedal return spring, GM #3921656. This is the clutch pedal spring that attaches at one end in the hole on the cross shaft upper lever, just above where the pedal rod attaches. On the other end it attaches to the steering column bracket on the firewall.

Can anyone provide the specs on this spring (overall length, number of coils, coil diameter, finish, etc)?
Appreciate any/all help in obtaining this info.

I have NOS examples [none for sale] but none that are easy for me to get at. I do not have the free length but the coils are 0.65" OD, 33 coils, and gray phosphate finish.

Joe,
Thanks for the spec information on my clutch pedal spring (GM #3921656). You help me solve one of the springs that has been laying on my part shelf for a few years. For your information the "free length" of the spring is approximately 2.375"

Also was wondering if you could possibly help identify the spring that's shown on the right hand side in the photo.
The coils are 0.625" OD, it has 44 coils and its' "free length" is approximately 3.0625"
Any thoughts on what it may or may not be?

I'm not sure what the other spring could be. There really aren't that many coil springs of this type on a 1969. The only ones I can think of are those associated with the clutch release system, those associated with the headlight actuating system, those associated with the deck lid release on convertibles, and the one that's part of the parking brake cable system. However, the one you picture does not appear to me to be any of those.
