Bring my 73 dart swinger back to life.

When I got this car, the wiper arms were disconnected and laying on top of the heater box. I installed all new everything. But the 2 drive arms.
#1 is the right wiper. Note where it is.

#2 is the motor arm.

#3 Is a picture of both arms.

The wiper arm is extended as far as it can go to the left. Now look at the motor arm. It appears to be about 90* off. I think. This is where I need help. Not knowing if I have the correct drive arms. My drive arm seems to be to long. Maybe someone can measure their drive arm, from the motor to the left wiper connection.:coffee2:
