Unfortunately, what Dan found is about the only thing available on trim paints.
Testors (the model paint guys) have an "Insignia Red", which appears to be a "standard" color like the Federal Safety colors. If you can't find someone who can match it for you, that would probably be "close enough." The only way someone could tell if it's wrong is if you parked next to an original truck, and that would probably be faded.
Can't help much on the "Dull Black". You've probably seen that there are about a hundred or more black shades, and gloss levels.
