Here are the best pictures I can get. Looks like the bracket is part of the windshield wiper support structure. The part of the hitting it is the "motor" mounted to the back of the plenum.
I thought that would work, but taking off the plenum showed that it was the top of the plastic variable runner box tapping against the underside of that bracket. I would have to reduce the thickness of the whole bracket.That's strange, I run a 26 and don't have that issue. I would carefully clearance it with a Dremel.
