I'm reassembling my windshield wiper assembly on my '70 Z after replating all of the parts, and the torsion spring on the pivot assembly at the motor/gearbox is broken. I also have 2 other windshield wiper assemblies which have the same broken spring. This is evidently a common thing?
I did a search of all of the windshield wiper related issues and found nothing.
I have a couple of questions:
1. What is the purpose of that whole spring assembly? I've analyzed it and can only figure that it might be for protection of the motor and gearbox if the wipers were frozen to the windshield or something. Part of the problem with my analysis process is that I don't know how or where exactly the spring ends attach since the ends are broken off all of three of the springs which I have.
2. Does anyone have pictures of a good assembly and unbroken spring so I can see what the spring is supposed to look like and how it attaches?
In talking with Z resto shops, I'm told that the whole arm assembly is NLA, which is the way it has been repaired by most in the past. I think I can manufacture a spring if I know exactly what it is supposed to look like and where the ends attach. I'd also be willing to buy a good spring if anyone has one.
Here is a link to pictures of the assembly portion I'm referring to:

The pics are acually from two different assemblies that I've taken apart.
Thanks for any help anyone can give.
