I am not a paint guy, but I tried to buy some b7, to cut the doors and trunk in, I told the guy that it was a color on some of the mid-sixties mopars, He mixed a half gallon, and it was like a b5. After he checked, Dupont had changed the codes a few years earlier. This was in 2001, when I did this, he said they had apparently changed it in the mid-nineties. I dont know if this is true or not,but I do know it didnt match. Good luck, John
