Chevrolet forgot to install a clutch return spring on a 63
I was surprised to see that the C2 does not have a clutch return spring like the C1’s. Because of a weak left ankle I was planning on replacing that spring but as noted there is none there. Does anyone know of a bolt on mod to add a spring (do not want to weld on frame). According to previous owner the pressure plate is original to car and would be the diaphragm type, which I guess is the softest clutch available.

Say what ???
The spring is not like a C1 but it is definitely there....on a '63 it attaches at a firewall hook. Item #18 in this '63 AIM pic... This is separate from the smaller anti-rattle spring at the other end of the bellcrank lower down...at the clutch fork lever...

Is that the same spring pass cars used on the clutch linkage under the dash? Corvette used it on the frame?

If you are referring to the clutch over center spring under the dash on a C1 that uses a three finger clutch, that spring was to add extra force to push the pedal down. Not return the pedal until it's at the top of it's stroke. It's not needed with with a diaphragm PP.

Dunno, Mike - I'm not familiar with the passenger car clutch linkage under the dash - if Verne is around, I'm sure he'll know. The "Godzilla spring" arrangement on C1 Corvettes was anchored at the frame, in the engine compartment.

What I'm saying is I would like to have more help in depressing the clutch like the C1 spring helps, even though the car does have a diaphragm.. My car like Frankie has the spring that he shows but that spring does not aid in making the clutch easier to push. If anything it adds a little more force to overcome but very little since the spring is small. Right now I'm doing OK with pushing the clutch down but if it gets to be to big of a problem, maybe I can get with a vendor and find a more lighter diaphragm clutch.

I drive both an original C1 and an original C2. The clutch effort on the C2 is easier to my thinking. Not sure how you improve on that.

I sent you a PM on something cheap, easy to install that you might try and I used on my '67 Chevelle.

If the OEM clutch is too hard to depress, I would suggest converting the car to a 700R4 automatic. If you simply try to add springs to lessen the effort, the clutch will disengage and never return to engagement.
I have no Gorilla spring on my '61, as I never had a B&B clutch installed in the car from when i first built it, Trying to put a G spring on it now, would just hold the pedal to the floor, IMO.
