It was part of the "Special Decor Group". This group consisted of the following: Woodgrain Applique on dash, two-tone hood, knitted Comfortweave vinyl seat inserts, bright wheel lip moldings. V-8 models included E-70x14 wide oval white sidewall tires, Argent SS wheels with plain center caps and trim rings. This group was also call the "Sports Trim Group". As Doug mentioned although listed as "Special Decor Group", many of these items could be ordered seperately.
Myself, I would prefer not to have the bright wheel lip moldings. They caused many cars to rust much faster around the wheel wells due to water, dirt, snow and salt being trapped between the molding pieces and the wheel well.
