Designed to complement the Continental’s unmistakeable radiator grille, these have the same look and feel of solid metal, but have been engineered with a unique lightweight metal. The unique chroming process includes copper encapsulation and then a nickel and chromium plating.

From the bentley web site. How much does this part cost and installation? What do they do to install them and what happens with the recessed grille already there?

 

I'd like to purchase a set if they look OEM as far as plating match
