T5 Blackout radiator support

Hi all, as my car gets closer to getting ready for paint I have a question. I’ve heard originally the radiator supports were blacked out on most cars spare the occasional light car and “dark colored cars”. It’s a 69 barracuda originally T5 and it’s going back T5 (bronze fire metallic) however there was too much paint over the original to tell if it was blacked out at some point. Is anyone able to tell on average if this color was still blacked out or not? Have any pictures of original blackout for the painters? Thanks.
