how the hell did u install ur billet grille?
If you like the fine slats, then you should probably just figure out a way to make it work, tack weld some brackets on there to get 4 self tapping screws into, and just screw it right into the fascia (after you black it out). Basically mimic the stull mounting approach.
If you decide to get a stull, I got mine at summit. Might be better places but you can still get it there.

I wouldn't worry about it. You could always get slightly larger screws, like decking screws. Basically drywall screws but with a zinc plating on them.
It seems to me the screws are grabbing onto the bumper foam as well, not just the thickness of the bumpe itself.

Try that first. Otherwise, any good owner should be able to figure out a solution with zip ties, jb weld, epoxy, and spare metal parts that will work out and look good. Just do it.
Remember, anything you do to the area the bumper would be covered up should you take it back to stock. So there shouldn't be a lot of tension about drilling a couple new holes. Just do it.
