technically correct maybe...but how about 'door window post'? Was not obvious looking at that photo.

To restore it will require removal of the hard anodize finish, repair of scratches and blemishes and then re-anodizing.
Check with the companies that restore Fuchs wheels.
Or Pauls Chrome plating in Pa.

buy good used. If you need more perfection from there, renodize in bright finish.
