GG makes them, part number 93324, 6.95 for four. They are plastic, I got mine at the Goodguys in Del Mar a few months ago. People love them. People ask me about those, my license plate frame (in fact member Bob from Texas emailed me about it, a Billet Specialties one), and my antenna that I also got in Del Mar. Some guys were selling chrome and colored Billet ones that they just started production of(I did not save the package) and I have not seen any since....I bought it thinking it would look good on the car before it came in and people are always asking me about it. I wish I had saved the box because I have no idea who made it, it was a small outfit in CA.
