1972 Chevy 4x4 correct colors?

[collisioncenter]

Hi guys, I'm working on a customers truck. Doing a 3/4 restoration the pickup was originally purchased new by his father and someday will be his sons. That being said I have the thing tore down to the chassis. He doesn't want to spend the money to blast and rebuild everything, however he wants the chassis painted and of course the body in show condition. He is going to drive and enjoy this pickup. My question is does anyone know the correct colors for the rear end, transfer case, transmission (SM465) four speed manual. and the front end. Obviously the motor was chevy block orange. Just want to get everything else right while I've got them out.
