I agree with Mike. I've put more than a half dozen E body windshields in, and never seen anything like that. There are 2 spacers that go at the bottom of the windshield opening, and most of the time the old ones are salvageable and can be reused. If they can't, the seal kit comes with some generic ones that fit at the bottom of the flat part of the opening instead of the 2 places the factory put them.
