Early A wiper assembly question

okay- 66 Barracuda- so before the wiper assembly (wiper transmission) goes back in the car, I took it apart, glass beaded it and clear coated all the parts before its resealed and installed while the dash is out.

I found the connection points under the retailing clips have a wavy washer and a round spacer that feels like felt. About .079” thick. Mine are shot. Everything else is good. Does any one know where to find them? I did a search on here and got no where. Either I’m calling them wrong name or it’s been a long time since the question was asked. See picture with my finger pointing to the felt washer.
Thanks!
Joe

They are called "Wave Washers", I googled them by that name, image of an example.
