I've been trying to remove the grill from my 1996 Mercury sable, and I feel 4 "clips" at the top portion of the grill. How can I remove the grill? I don't want to break it, and somehow these "clips" are keeping it from coming off. I don't want to break the clips either, and I've taken out the screws for the turn signal assemblies as well as the ones holding in the bottom portion of the grill. Does anyone know how to get the darned thing out? Thanks for your help.
