I should've taken more pictures of this portion of the project.

You'll need to remove the entire air intake screen that rests directly below the base of the wiper arm.

First you remove the grey rubber trim pieces at the base of the windshield. These are pressed on with a friction fit. (I got to the wiper assembly without removing them, but had to pull them off in order to re-assemble all the other trim pieces.)

The screws for the two drip rails on either side of the intake screen reside below the grey trim pieces.

Remove the two little hidden screws holding the intake screen to the body (see pic).

Then remove the screws holding the crescent ring that retains the rubber bellows below the base of the wiper arm.

There are a few other trim pieces that're part of the sound proof insulation, but the rest should be fairly obvious.

Remove the intake screen, which reveals the wiper assembly and linkage below it.

Here's a picture of the air intake with everything removed (except the windshield trim pieces [I.]) There are two nearly hidden screws that hold the intake screen to the body [II.].
