Bronco II rear wiper arm

[tcourtland]

I can't for the life of me figure out what the correct part number is for the rear wiper arm. So far I have found these 3 part numbers on fordpartsonsale.com but with no accompanying pictures:
- E4TZ-17526-D
- E6TZ-17526-A
- E7TZ-17526-A

Anyone able to help me out? I just want to be able to wash my glass from my seat.
