I have a the standard model of the 2007 grand prix and wanted to make the outside a little better. I was wondering if anyone knows where i can get some CHROME grille inserts for a good price. Also, i know on the older models of the grand prix, there are 2 screws to get the inserts out, well there are no screws on my grilles and i cant figure out how to get them out. Can anybody help me? Thanks
