The 1966 Valiant bezels are skinnier, the Barracuda ones are thicker. If you don't have them side by side it can be tought to tell. If you look at your Valiant bezel (off the vehicle), look at the side that mounts towards the center grille, it is about a half inch wide where it is smooth and shows. On a Barracuda the smooth edge is about an inch wider. I think this is because on the Barracuda the grille is recessed a little deeper, therefore needs a thicker bezel to line up with the head light. You can mount the Valiant ones on the Barracuda, only problem is you will have a 1" gap between the two. Becareful of what some sellers (ebay) will tell you, they are not the same!
