I have never seen that rubber bushing. Need to see if I can locate one somewhere.

PWH42..... The link or rod attached to the large spring on the pedal under the dash has fine threads and about 2" of length adjustment.  I have adjusted the length of the link from one end of the threads to the other and in every position the pedal is being pushed downwards instead of returning to the uppermost position equal to the level of the brake pedal.  I installed the large spring and the two pieces of the link just as shown in the diagram in the shop manual.  Alan

The light spring is to keep the actuating rod from rattling and falling out of the clutch arm.The heavy spring under the dash is designed to go over center.At the top it holds the pedal against the upper stop.Halfway down it helps to disengage the clutch.

Question....which spring or springs cause the clutch pedal to return to the same level as the brake pedal?  It looks to me like the pedal return results from the springs on the pressure plate and/or the clutch disc.  The rather lightweight spring next to the adjustable rod looks like its purpose is to make sure that the rod remains in contact with the clutch fork at all times.  The spring on the pedal assembly under the dash looks like it is designed to make depressing the pedal easier for the driver.  Anyone know the answer to this?  Thanks, Alan

I adjust the free play so ther is 1in free play after the lower spring is cmpresed and throw out is engaging. other wise you have to much fee play. the lower spring is designed  so throw out bearing is not turning till the pedal moved 1in. as the clutch wears the 1in will decrease,requiring adjusting the rod to real ease lever so the 1in comes back

My setup has both springs but the one down below next to the adjustable rod seems to be a rather lightweight spring although it was the one which came with the car and the clutch worked well before I disassembled the car for restoration.  Am I correct that there is not supposed to be any movement of the adjustable rod during the first 1" of free pedal play?  Thanks

Alan,
I ran across this in the Thunderbird Restoration Manual a coupe of weeks ago and may apply to your problem also.
"Pgs 252-3 Photos 17&18.
Photo 17- The clutch release equalizer ball stud should have a thick rubber washer and the half round bronze bushings to function properly.
Photo 18- Shown are the rubber washer and bronze bushings in place. They slide into the release equalizer bracket that bolts to the engine. In most cases if the bronze bushings are missing the clutch pedal will not return fully."
Attached are not the photos but a capture from the illustrated parts breakdown Pg 218.
They would be the two piece brass bushing # 7517 and the rubber washer # 7539.

The first inch of free pedal play does not move the rod at all which I think is the way it is supposed to work.  Alan

My buddy with a 55 Ford has had problems over the years with chattering in the clutch.Discovered this week that the overcentre return spring on the pedal under the dash was missing.Put one in and the clutch has never worked better.I would assume that the clutch was not releasing completely previously.
