71 Dart Battery Tray?

Supposed to be body color....just like the rest of the engine bay. I just repainted the one in my Challenger yesterday because it was turning to rust color in places....lol. The belief that they should be semi gloss black started 30 years ago when people started buying NOS battery trays that were semi gloss black with white part numbers stamped on them, and just bolting them in assuming that was correct.
