Mazda3 trim piece
 

Does anyone know if such a thing exists? I want to replace the shiny black trim piece on the dash, the one with the radio/temp screen cutout. I want a solid piece without a cutout for the screen, since i am upgrading the H/U and will lose the use of it anyway.

look on ebay, they sell carbon fiber 'look' kits, they may have the whole plastic pieces as well where you need to do the cutout part.
If you're covering it anyway, you should probably fiberglass the whole thing or something like that.

I have looked on ebay and many other places, and haven't found anything, i may try to wrap it in leather or vinyl to match the dash.
