Thanks - that looks like it mounts to a hole drilled in the glass? But you said it's to the windshield frame?

If you can get dimensions you might check in McMaster's list of rubber bumpers. I bought a bunch from them years ago, including one I mounted at the front of the door jamb to somewhat simulate the original front door jamb bumper on my ERA. I'm sure what I used is not dimensionally correct but the door jamb clearances on replicas will vary from the originals.
