Recently purchased a billet grill insert via ebay for my 03 Silverado from dalesbilletsales.com. Fitment and looks are good.

The bad is that I had to spend time shaving some of the screw heads down to fit between the billet and its attached with toggle bolts (which I hate!!!). I will replace the toggles in the near future.

Overall, for the price ($25 plus s/h) it was a good choice. It came in an expeditious fashion too.
