The Iris Mist as also called Evening Orchid on Chevrolet models. I got mine from Model Car World Automotive Finishes. The paint division of MCW was sold off a while ago but they're still in business. The problem maybe getting the paint over there. I really like how your build is going. You mentioned the Aztec Bronze color, there was a '66 Chevrolet color by that name by the way, and from what I could see on the underside of one of your interior panels that would also look good.
