Rebuilding wiper mechanism

[Randalla]

I'm in the process of cleaning, lubricating and re-building my 240Z wiper mechanism. Noticed when examining everything once it was out of the car that it appeared to have felt washers as part of the pivot mechanisms. Mine were rotted/unusable but I assume I need to find some acceptable replacements as they must serve  some purpose. Seems like nylon washers might be a more durable alternative. I believe there are either 3 or 4 used in total. Has anyone replaced these parts with something that works well?

I used the circular anti-corrosion felts for battery terminals. They came pre-punched for the terminals to pass through.

They came several to a package and although they were Christmas-y, (red and green), they worked well for me. I slathered them in Lubriplate bearing grease, working it into the felt and then re-assembled.

Four years later the refurbished wipers work as new.

Great idea! I assume from the picture that you just used the inner felts. Appreciate your response as those are readily available.

I would assume that those battery washers have some kind of acid neutralizer in them,  it will be interesting to see how they hold up over time.
