Hey, sorry it took so long to get back to you. Had a big lunch day out today with some other Bronco-bros and just got back!
Ok, so that's kind of what I was thinking you meant, but wanted to make sure. Looking at that bit, it's almost like a little "pedestal" that the windshield hinge sits on.
Looking at four Broncos, as I figured all four were different. The gaps were from about 1/4" down to zero. Literally the fender touching that bit of the cowl just below the windshield hinge.
Here's my passenger side at about 1/4" approx. In glorious "BPC" (bird poop camo) Fall coloration.
