Loose Cuda wiper arms

My wiper arms a really sloppy due to wear so I have A couple of questions.
Has anyone ever peaned the rivets that hold everything together in an attempt to tighten the linkage?


Also, there is a small linkinage that connects at the base of the wiper arm and I’m trying to figure out how it comes off.
Is there a tiny E clip holding it on?


Thx

I would peen them.This is the clip that you need.

That is one tiny SOB.

I see that R/T Specialties and Megaparts has them.

$10 each.

Thanks

I have put them I vice and gently squeezed them and it helps
