Engine Bay Component Paint

Does anybody know who sells the best black paint to be correct for painting the fan blades, radiator, horns, breather, blower motor, regulator etc on a 1969 Dart Swinger?

The 340 is painted blue. Classic Industries has paint that they call turquoise for that engine. Layson's calls it blue. NPD has blue with the Mopar M logo on the can.

I also need to respray the bottom part of the grille which is gray or silver.
