JB007 Tailight approval can be a personal choice thing in my not-so-humble opinion. As an example, I NEVER liked the Tail lights on the '67 Mustang that I once owned, they were 'concave' design setting the model apart from earlier models. I much prefer the tail lights on the 1966 Mustang, because they are 'convex' and look neater. The perfect look would be the Front & Grille of a '67 but with the Rear look of a '66. My mechanic feels the same, and he has had a few 'ponies' in his time ! Blue Stang Concave Tail Lights ~ Red Stang Convex style
