My all original 66 L72 is Aztec Bronze with a fawn interior. From what I understand Aztec Bronze was '66 color only. The picture of the 'Untouchable' above looks to be the same combination.
Well we have a winner!!!
I have looked at all the colors available. I have saved all the pics I could find to see which combo I liked the most. My car currently has a crappy maroon paint job that looks to be 30+ years old. I assumed maroon was the factory color and since my friends '66 Caprice is maroon I didn't want to do mine that color. I just ran the trim tag and it was actually a factory Aztec Bronze over Fawn car. That is it, the combo it will be!!!
