Winshield Wiper Assembly??

Yup, there's a wavy or spring washer and a flat wear washer at the top.
Shortening the right hand wiper pivot by 5/8" was a necessary evil in my DIN rallye panel mod, so now I know how to take the entire pivot assemblies apart. LOL
After tweaking the arms and new fillers, my wiper have never operated so smooth and quietly, even on a dry glass.
