Billet grille

Anyone that has read my earlier thread knows I got in a fender bender and messed a couple things up... My question is with a billet grille insert... Does it completely replace the existing stock grille or does it just attach to the OEM grill??? I need to completely replace the bottom and top grille and do not want to get something that still utilizes the existing and now broken stock grille.. Any help would be greatly appreciated, Time is of the essence

 

Here is my grille I got it from performance products and I had to cut out the old grill to install the new one.

 

I rear ended someone and the clips are messed up on on the grill and the bottom grill is pretty chewed up too, im gonna be getting a new bumper, with grill and headlight and all so I thought I would save money and just get a new grill myself ... But I need it to replace the stock grill, not modify it b/c of the broken clips behind the grille

 

These are the broken clips... The one directly in the center of the grille

and the one that goes into the headlight assembly on the passenger side

and here is the grille on the bottom
