Am restoring a 64 T Bird, what is the correct firewall and engine compartment color, are both the same as body color? I've seen a lot of pics with the engine compartment body color and a lot that were black.

I have an originaly raven black '63 Fairlane with a red interior which I'm restoring. So I'm wondering what colors were available for the stripe along the side of it. Does anyone here have any knowledge of the paint schemes used?
