When I purchased my 67 it had an incorrect 68 grille on it. I have purchased all the parts for the 67 GT grill so it will be correct, but not sure how to assemble. It appears that one end of the corral actually goes through the support of the grille, but the whole is not large enough. Is that correct that it should go through? Do I simply need to enlarge the hole so it fits? If anyone has a 67 GT that could provide me pictures of the back of the grille it would be appreciated. Here is mine.
