I've posted this also under general discussion because I am not sure where it should be. Does anyone know how the upper dash (metal) is installed on a 67 Camaro? The reason I ask is on the passenger side inner door (hinge pillar?) just above the top hinge and below the front windshield, there is a bolt with 3 washer on it. I tighten it up as far as it would go and it just spins. Reason I ask is I have developed a "squeak" behind the glove box and was wondering if this bolt could be causing it. There is nothing on the drivers side like this. It "appears" this bolt and washers have something to do with the upper dash but I am not sure.
