The fog lights look "correct" on Markeb's truck, but I think it is because of the GMC grille. Not sure you can pull this same look with the 63-66 grille styles.
That being said I too am a big fan of fog lights, and the owner of a '65 C10.
Woog, prove us all wrong and make it work, based on your knowledge and skills I am betting you can do it!
