The Formula wheel was installed in '69s built 9/15/69 and later (due to delayed introduction of '70s). It replaced the Custom Sport (wood) Wheel and did not have a unique order code. If your Formula wheel is original, it should have round holes in the spokes and the 'bird with turned-down wings on the horn button.
