I have a 2008 chevy impala LTZ and I am trying to replace my headlights but I cant locate the name of the plastic cover that the retainer clips clip to. In my Haynes book its called a radiator cover but I think thats actually the cover on top of the cover I am asking about. The part is cracked and need a new one to replace headlights.
Thanks

 

If you take the part you have, and give it a real close look. Do you see any part numbers molded into it that may help identifying the part?
