Don't know that anyone has posted what the exact matching color would be in new readily available rattle can color would be. Have examples of originals but don' think that will help. Have painted them in the past but don't know brand, color name or code so can't recommend
Only recall that a close match was one of the many Ford corporate blues that was available locally
Sounds like a test is in order unless someone can offer a personal recent experience of what worked or even didn't
