Yes, I believe that I do. In 1967, the Fastbacks came "Standard" with Full Wheel Covers, while the Coupes and Convertibles came "Standard with the small, "dog dish" type Hub Caps. If Styled Steel Wheels were ordered with the Fastback, Ford was basically giving the purchaser "credit" for the difference inn price between the Hub Caps, and the Full Wheel Covers.
Hope this answers your question.
