I literally enlarged the images on the CJ3B Page of the paint codes and took that with me to the paint shop. Only one paint store had issues. I'm really not sure why they had problems but I did what anyone does with anything else: Go to another store.
When I handed them the sheet and pointed at my color, I asked them if they could make it. Two shops, one in Kansas and one here in Alabama simply said, "Of course." Both were very accurate. I will also say I went with the 2-stage tone and clear coat.
