I'm not sure bud, I always have the body shop do these little jobs for me.
A good way to go about these things is go to a GM dealer's body shop, strike up a convo with the manager, and have him paint your stuff when he's doing another vehicle your color. That way he's using left over paint from another job and charges you very little.
But a small job like this, to paint both bowties, shouldn't be too expensive even if he mixes the paint just for you.
If you want to do it yourself, your paint code should be in your glovebox.
