i took of the old grill the new grill fits good but it shows the old holes that the old grill have what should i do to replace those holes

 

K what kind of car, what kind of grill, where are the holes. You need to supply this stuff for good answers.

 

its 2000 gt billit grill and there are some holes that i dont like

 

I imagine they are holes on the top of the bumper?

If that is the case you could go to the auto parts store and get some interior trim clips, you knwo the plasitc chistmas trees and put those in the hole, or you could fill it with body filler and paint it.

 

you may have to get the grill delete kit ,,,that what i did to my wifes v6 but didnt have billet grill ,,put that plastic peice covers up the holes on top of the bumper,,
