Paint color

I have a 69 barracuda I'm fixing up can anyone tell me what the factory colors were for:

Door hinges
Hood springs
Hood latch
K-Frame

I think some were body color, while others were not. Thanks.

1. door hinge = body color
2. hood spring = body color
3. hood latch = ? (either black or body color, I'm thinking black)
4. K-frame = black
