Hey guys - I had Jules restore a 3 speed wiper motor from my 72 Challenger. Got it back and looks great, but the linkage does not line up with the stud on back of the motor. The motor was in the trunk of the car when I got it, so I can't confirm how it was connected before.

The part # on the motor is 3431624 and the part number on the arm that slips over the stud is 3431635.

The motor is in park position and the arm is about an inch too far forward to slip over the stud in back of the motor. An ideas for me? Thanks
