From parts I have "on the shelf" at my storage. The 15" Sports Wheel Covers with the "football" shape hole carry a D0 part number, the 15" Sports Wheel Covers with the "racetrack" carry a D1 part number. I do happen to think that on a 1970 BOSS 302 these have a very different look to them. I'm glad that our 1970 BOSS came with these wheel covers and also glad to have a spare. Pretty rare option.
