Thanks for the reply. All GM vehicles were painted in laquer until around the mid 70s I believe. Even if this would have been a Mopar color, it still would have been laquer although Mopars were using enamal back then.
Any chance the original owner is still around, or any paperwork on the car with a mixing formula possibly on the build sheet?
If you look at a chip of 70 Caddy Chateu Mauve firemist poly, it is lighter, and more vivid than plum crazy.
Was there much overspray on the floor pans on the inside of the car? These -- cars are very interesting, and sometimes hard to get a handle on the original color without an original owner, or paperwork.
