In 1970, the Rallye wheel was 15" in diameter. The numbers don't mean squat unless you want to have EXACTLY the correct wheel. The important thing for looks, is that the trim rings and center caps are correct. Yours look great in the picture, but the centers look a little bright. If I remember correctly, the centers were dark Argent in 1970, and the wheel was light Argent. Date codes and correct stampings for production line, etc, are for those interested in concours correctness.
