Wiper arm and a body plug.

I don't care for it either, but have to do it all the time.
What I hate even more than the rain is when it rains just enough so all the other cars make a big *** mess of my windshield. :D

THAT prompted me to build and install a large capacity washer tank with a good powerful pump and to slightly drill out the squirters.
It's mounted on the passenger side inner fender and uses an inline electric pump that works normally with the wiper switch wash button.

Hey your right there is only 1 bushing I just took a better look,sorry my BAD.
