If you really want to get crazy, buy a zinc-plating kit from Eastwood and plate it! The zinc will give a factory look on the tray itself and on the frame, and of course you can paint the outside to match your dash. You have have the whole thing absolutely clean before you try plating it. I wash my parts with Auto Zone carburetor cleaner and let them air dry, then in the acid they go. The Eastwood kits are fantastic--you can replate nuts, washers, screws--anything that came zinc from the factory--make them look brand new, save money and keep your original parts! On my '68 I've done the tie rod sleeves, suspension nuts and washers, brake components--etc. People are amazed when I tell them they're the factory parts. Just a thought. Good luck!
