I am posting some pics of my 04 40th Anniv GT Coupe. I have seen the rear window louvres on the 03 and 04 Mach 1's and liked them, just like on the 69-70 Stangs. I have even seen a few GT's with them that looked good. I was thinking about adding one to mine, but I am still undecided. What do some of ya'll think?
