Fwiw

You don’t need the spring, and you will not miss it.

While everything may work fine without it, I think I have discovered why they are there.

I did not put mine back, in part, knowing I am going back inside the doors again (and again) to fix a few more things.

 

On the passenger side, the window crank has taken a little bite out of the vinyl.

 

I suspect the springs are used to take up the 'slack' in the panel in a way that insures a lack of interference.  I stuck the fuzzy side of some Velcro tape to the back side of the handle to protect the vinyl.

 

VW used them as well, but the spring is a little heavier.  Actually, my '72 Suburban uses them too and I've taken some other trucks apart, so that could be a GM spring on the right.

I bought these for the heck of it, to see if the springs would work. They are almost identical size as the vent window spring.

The conical spring is similar to what is used on old GM door panels.

I am also in the camp of installing the springs behind the door panels.
