Damn where were you 2-3 weeks ago when I needed to swap my black ones for chrome!
You're not going to find many of these for sale. The regular Mazda 6 has a different sized front emblem, and the MS3 emblems don't fit. I'd recommend just removing yours, scuffing them with sandpaper and primer and paint your stockers. That's what I did, turned out just dandy, and it was cheap.
