Mk2 on Minis had a multi piece grille trim with two sides and one bonnet mounted strip. Often the sides are damaged, discolored, or even fall off. No need to purchase a complete grille, as we just have the surrounds availible. This is the right hand side while sitting in the car. 
 
Also make sure to get a replacement edging strip as this is not supplied with one. (WC-37H8108).
