Paint Color ID, Help??

[76PasoGMC]

Ok guys I just got a 76 C20 that I will be using the cab on my short bed step side. I want to paint it the original color because it has family history (wife's family)

Anyway can anyone help me figure out what paint color this is. I know its original paint. The interior and door jambs are Perfect, so I only want to shoot color on the exterior. I have enclosed two pics one of the outside the other of the interior. I have the paint chips on line but the colors don’t look quite right. I looked for the options tag in the glove box but it is gone.

Thanks for your help I am swapping cabs this weekend ands will be starting body work very soon.

here is the link to the paint chips for this year truck
