1972 Paint Codes

[crustysarge]

I am a little confused, I have a 72 Cheyenne Super that has option 542, Medium Blue/White. Yet I see Mariner blue was an option for 72 and Medium Blue was not (according to brochure). I also used this link:

This shows Mariner Blue but no Medium Blue for 72 and Med Blue for 71.

What is it, Med Blue? I need the paint codes and I believe Med Blue is 521 and the White is 510? Yet Mariner Blue is 523. Which do I have?
