1972 K20 in KY

[dave6672]

Hi I'm Dave6672 from Kentucky. I have a 1972 Chevy 4 X 4 3/4 ton long bed stepside. It has a 350 with a 4 speed and is currently undergoing a (very) slow restoration. Does anyone have any information about the paint for my truck? According to the glovebox option sticker the color is Medium Red, option number 151410. However, this color is not on the PPG paint chip guide for 1972 Chevy trucks. My body shop has already painted the door jams and it looks too orange. I want to make sure they are using the correct color. Any information on this color would be greatly appreciated!
