I just purchased a 2011 HHR with an aftermarket Billett grill. I don't care for it, so I purchased a new Chrome Grill that looks like a factory OEM grill.Can someone tell me how to change out the two grills.When I remove the billett grill will I need any special GM fasteners to install the factory grill

 

Depends on which one you have. Most use the original fasteners and should be straight swap. I think its just 5 nuts.

 

thank you. the grill that came in it looks just like the one in your photo. the new grill i got came with no nuts,or fasteners. that is why i did the post

 

Simple.
Pull off the aftermarket grill. See what fasteners you remove. Match them up to the new OEM grill. If you don't have the correct ones or right amount, then a trip to the hardware store is needed.
