I have remediated my problem with water ingress to the cabin, cleaned the SJB so it works again (whew, lucky) and am installing the windshied wiper cowl grille pieces. The pieces are a bit warped and not sealing well against the windshield.

The rubber strip is integrated into the plastic and replacement cowls are rare for this model making them expensive, so I am considering using black self tapping screws to fasten them just above the holes where the original clips are located. I will align them as best I can to look "factory". I am hoping someone else has done this before and can provide some pictures of how it ends up looking, with or without caps on the screws. Thanks in advance for any suggestions about this.
