Take a look at the photos I posted here:

You should be able to get pretty close by looking at the photos.

Worst case scenario, put the wiper motor back in as close as you can get it. Then run the wipers so you know the motor is in the "parked" position. Finally, remove the wiper arms and reposition them so they're in the right place.
