I recently got my first z28 and it has the holes for the fog lights with a screw hole in each corner is there a bracket to put fog lights in it or do they just screw to those holes. There is no switch or wiring in the car for the fog lights. Thanks

I saw some of those brackets on Ebay a couple of days ago.

Or do they make a grill insert that will cover the whole opening where the license plate and fog lights are?

you can use a base RS grill to cover where the fog lights go.
