Grill restoration company's? (pics)

Guys, correct me if I'm wrong here........

Wasn't 67 the only year for the anodized aluminum surrounds? 68's and 9's all look to be chromed instead of anodized.......Correct?

If so, they're probably not aluminum........Don't know.......somebody speak up here.........

Question.......Are 68's and 9's the same in configuration as the 67's? Are they interchangeable? :read2:
