Rupp color code

#1
Does anybody have a color code for the purple used on a Rupp Rascal,71-72? The paint jobber I use will mix me a quart of the old Dodge color,plum crazy in urethane,but if I can be more accurate I will.I can cross from almost any brand of paint.It looks to be a little more pale than the plum crazy,but it could just be 40 years of aging.We cleaned up a spot on the bottom and hit it with the Prophet,(color scanner) but he said it is evidently reading a deep component of the pigment.The formula comes up as a yellow.
