rcborst,
Tim is correct to try to steer you towards, Denny Grahams posts. He took a lot of time to find the formula for the interior color, for our AD trucks. I used the color that Tim is referring to, in my 53 3100. It came out great. There is also a slightly lighter color that shows up on glove box, ash tray and speaker grill. We can cover that later, if you would like. For now, here is the color code that Denny came up with. It's PPG 27467 Graphite Brown Metalic. You have to add some flattener to it. Otherwise, it is to shiny. I wish I could tell you how much. I had some mixed up about 10 years and painted my interior with that batch. Then, just about a year ago, I had some more mixed up, by a different paint store. This time, just into a couple of rattle cans. Wanted to be able to touch up places and finish painting some of the interior parts, like the glove box, speaker grill and ash tray. If you would like to PM your email address, I would be happy to forward some pictures of the finished product.
Hope this helps your restoration.
