72 Cheyenne Super Interior Colour help needed

[3sonsdad]

I am changing the exterior colour of my truck from solid black to Medium Blue/ white but want to retain the black interior. I will be painting the interior of my cab medium blue to match the outside. Can someone say for certain if all of these items would be black if the truck would have come from the factory with this blue/white exterior- black interior colour combination?
