The only useful paint chip chart I found for my Aero was Ditzler since they still exist as PPG, and the company I used had the PPG formulas.
One other thing to consider is that the original paints had smaller "grain" metallic particles that are not as "bright" as the modern metallics. I describe it as more "velvety". The company that mixed my paint not only had the correct metallic for the body, but both sizes in the original dash colors, as well as the dash formulas, which as far as I could tell was "lost" information to the club.
I have no idea if they have any KF information but it may be worth a check. They offered my colors in lacquer, enamel, acrylic enamel and base clear. Base clear both in PPG and their house brand which is like PPG but cheaper. I went with house brand base clear and am very happy with it, as was the painter. It's a personal choice whether to re-live the maintenance schedules with the older formulas.
