I am replacing my front grille, 2 headlight style.  While doing so, I found the 2 mounts on the upper inside of the headlights are missing.  A result of the Carolina crash, no doubt.  The guys down there put a couple of small screws in place of the normal mounts.  My questions.  Can I expect the 3 remaining mounts to handle the load of supporting the grille?  If not, are they replaceable in some way, or should I use the screw method?
