The difference between a 67 and a GT/CS is that it has marchal fog light bars mounted, and the top of the grill where it mounts is a little different. Also, the 67 grill has inconsitencies in the grating to accomodate for mounting the 67 horse/corral emblem. These spots are filled in with metal, and you cant really just drill them out because you will end up with big holes where the grates don't match up.
