You should be able to just remove the top black metal cover, where the hood latch and GM Performance Division emblem is (or should be depending on build date).
That will allow you to reach down to the back of the heritage grille.
Would this work on a stock grill, I have a billet grill that goes on as a cover to the stock grill. Or should I just remove the front end to install the upper and lower billet grill..
