Last year when I needed an engine paint for one of my Ramblers I went to the local Dupont outlet with the old AMC paint code and Dupont paint code. The counterman couldn't find the code in their computer but he called a guy at the (Dupont) factory and they were able to pull up the code and he got the formula for the paint. You might want to approach your local Dupont guy about calling a central number for help with the codes in the future. I can probably get this phone number if you need it. Joe
