Wiper arm to motor comes up short

I had removed the wiper motor on my 98 Transport. I reinstalled it but when I try to reconnect the arm it comes up short.:confused:
The wipers are in the home position. Where did I screw up?

I cycled the motor thinking it was out of sync but that didn't help either.

Is the crank arm on this the solid one piece or the rotating one?
