Keith is correct. But on a 67 Barracuda these will look silly, because they have a ridge or peak in the center that doesn't match the nose panel.
You could use a 69 Barracuda nose, but the problem with that is that your 67 nose & grill set is about twice as common as the 69 set. Meaning you'd be swapping in the expensive direction.
I suppose a good body man could take just the center top area from a cheap, beat-up 69 Barracuda nose panel and splice it into your 67 nose. But it would probably cost just as much or more.
