Does anyone know what the hole is for? It looks like it's had a tool jammed into it.
Is it possible that Ford may have used that hole as a leverage, with a crude tool, to move the latch striker on the assembly line? Possibly when due to tolerances, bolt adjustment wasn't enough?
Looking at the upper edge of your hood latch support bracket, it seems uneven or canted as though maybe the holes in the radiator support are misaligned?
