Polished Aluminum Spinner

I am looking for a aluminum spinner for my 200HP Lycoming IO-360 A1B6, in my RV8. My propeller is a Hartzell C/S, Model HC-C2YK-BF. Has anyone out there installed a Metal Spinner, and where were you able to find it. Any advice will be appreciated.

What prop? There are some certified ones out there, but most are 14" instead of 13"
