I bought some Mission Model paint a couple years ago and decided to test it. They have a color that's called Irridescent Plum Purple. It's a real close match to Plum Crazy purple. It has a very fine metallic which matches the original Plum Crazy better than the new stuff from Zero and Gravity paints. The original had a very subtle metallic. You can try adding a touch of their red irridescent to see if you can get the color even closer since we all see red tones slightly different.
