I have a 70 Charger I'm restoring and I'm trying to understand the various interior colors. I believe (based on the Fender Tag below) it's a Tan interior (seats, etc), but when I look at things like armrests (which need replacing), I see several types of Tan/Brown (Saddle tan # 650, Brown #656, Dukes Tan #670, Copper # 620). Is there a source for figuring out which color I should be targeting?
