Restoration correctness?

I have some questions about originality on dodge darts particularly 1975 models. Let me start by saying I'm not doing a true restoration but I do want it to be as close as possible within reason and my limited skill set. My question is was there any part of the body IE radiator support, inner fenders, frame rails etc that was painted a different color than the body? Was it all the body color or did they black it out? I know the engine bay is body color but I'm not sure about the inner fenders I see alot of ppl black it out. I want it to look like it would have when it was bought new in 1975! Thanks for your help
On all of the A-Bodies i've seen, 1975 was the only year that i noticed that the paint in the engine compartment was absolutely terrible.
This is the only year that in the engine compartment, only the top part (maybe i foot) was painted body color, and the rest was bare dark greenish primer.
If you want an accurate finish, sadly, that's it.
The floors were painted similarly as well.
