I found the following two pictures in my shop manual and both show a spring connected to the peddle but not where it goes to.  A little research has also said this might be part number: GM# 3653114 that seems to be NAPA Part 615-1101.   Any of this sound right?

I'll try to remember to sneak out and take a look at my 38 later today. It may be the same.

Not the best photos and I don't know how this translates to a 1941 but the spring attaches to a tab on the engine side pan and a tab on the clutch arm on my 38. The spring in question is the lower spring in the second photo.

Here are a couple pictures from a 48 but the 41 should be the same.  Notice the tab bolted to the frame in the second picture that the spring connects to.  Also note that the spring does not hook into the eye of the clutch linkage as shown in the second picture, rather it loops around the clutch fork as shown in the first picture.  Hope these help.  Mike

This is a 40 truck.

Thank you all for the help.  We were able to track down the part and install it this Saturday.  Called my local NAPA with the part number and they still carried it.  They had to order it but it was in Saturday morning.  Had to get two since they came in a two pack and it was a special order.  Total came to ~$5.  Found the place on the frame to attach it.  We looped the spring around the clutch fork.  After doing this the clutch pedal is higher than it was.  

Glad you got it figured out.
