I looked up the exact colors, according to MCW ( www.mcwautomotivefinishes.com ) .
for '64-'67 Sox and Martin cars, the correct paint their order number 6452 white, 6436 blue, and 6238 red.
for '68 and beyond Sox and Martin cars, their order number 6452 white, 6853 blue, and 6861 red.
This translates to Mopar '64-'68 white for all cars...
For '64-67 Sox and Martin, the blue is Ford '64 Guardsman Blue Metallic and the red is Ford '62-'65 Rangoon Red solid.
For '68 and beyond, the blue is Plymouth/Dodge '68-only Electric Blue Metallic/Bright Blue Metallic, while the red is Plymouth/Dodge '68/'69 Bright Red (aka Charger Red, 'cuda red, and other various names).
