Mine started cracking, couple pretty bad but its all holding in place now, but if I were to take the lights out for some reason, no knowing if it will go back in straight. And I'm not about to find out. I ended up using smaller screws for the remaining 6 holes and it went well.

 

I installed my SS grille today and had the same issue. The OEM bolts made the stressed the plastic. The foglights are in solid, so I believe everything should be fine. SS should really cast the mounting points to be a bit thicker IMO or provide the proper screws. Otherwise, it's a good quality product.
