1972 truck color (Medium Red) - Help!

[dave6672]

Hi, I have a 1972 Chevy K20 long bed stepside that is currently undergoing a restoration. The paint color is listed as Medium Red (option # 151410)on the glove box option sticker. I can't find that paint color on the PPG paint chip chart for 1972 chevy trucks. My body shop has already painted the door jams and they look like they might be too orange. I want to make sure that the truck is painted the correct original color. Any information on this paint color will be greatly appreciated!
