A-body armrest - stripped threads in door’s sheet metal
Along the same lines, cut a slot above the hole and insert a U or J speednut of the appropriate size, threads behind the sheetmetal.
Or if you don't want to cut a slot, just JBWeld a flat speednut to the back of the sheetmetal.
Or, really cheap and easy- take a 2" piece of wire (doesn't have to be very thick), stick it halfway into the hole and bend it flat (in half). It will now hold the screw.
