What parts did I break fixing my windshield wiper?
 

I fixed the wiper assemblage the other day (macgyvered it, really), but in doing so I broke the white plastic piece that holds the two pieces of the assembly together and makes the passenger side windshield wiper move. I also broke one of the two plastic pieces that hold the cowl in place.

What are these two pieces called? I'm looking on parts sites to buy new ones, but I don't know what to look for.
