2 speed wiper drive arm.

I think you have that bushing in backwards, the 3 prongs hold the wiper blade in pace as the motor turns-- you look to have no way of holding the arm still --so it spins as the motor turns.
ok went out to the parts stash, the pics show a 2 speed bushing on a 69 dart arm, the white bushing is a 3 speed/varispeed unit-- notice the hole vs the circle orientation.
I do not have a crank arm for the 3 speed unit-- but the slot is orientated different from 2 speeds.
