Windshield wiper help

On my 2 speed there is an arm off the motor it connects to the motor with a metal nut then to the wiper arm with the plastic peice

And at least one of the other styles are connected with metal clips, and thers with an off center plastic bushing.
I suspect the OP has the large plastic off center bushing type from the sound of it.

Kinda like Nite Moves is going through here.
