OK @Topside I make a sample (1 pic) to Audi LY3J but Audi color it is too bright with my tag. I forgot I have tag with old paint not cut but in not good shape . In pic 2 it is GM 9260 better but it is like Red Bridght 331. I ask one more paint shop and they make me from Dupont PP1 they had recipe for it from 66-68 (Pic 3) But it is very dark. @68jim I ask PPG about 71966 no recipe @antonellomopar I call to my local Sikkens paint shop and they have recipe but the dont have 2 or 3 pigments and thay can sell it only 1.5 L becouse they need to supply it for me. And I dont wannt to buy it without making a sample of it. So that One from duponte it is probobly PP1 ? The pictures dont give it in full In the middle is dark red that one from Duponte left it is GM and right Audi pic 4
