These screw holes for the in-cab fiberglass heater core box were stripped out. They are for mounting the duct distribution/diverter box. After cleaning up the heater core box I did the super glue and baking soda trick again, this time to close up the screw holes. I ground the area flat and re-drilled them and tapped them using the original screws. Interesting that the head of one of the screws has concentric circles decoration and otherwise the screws are identical.
