Well, I'm back this weekend working on installing my interior on my 67 Charger that I took apart three years ago and I can't remember where this piece goes. This was in my bag with the rearview mirror. I thought it was mounted under the rear view mirror in the center and looks like it should be screwed into the center of the frame around the windshield before you put the plastic trim over it. I know where the three screws go to hold the rear view mirror onto the frame. Any help is appreciated.
