15 inch stock wheel question

[DoubleDlover]

theres a 73 in the local yard. I don't know what model. But its the same car they used for police cars. Has those big square rubber bumper knobs on the front. anyway. It has 15 inch stock black wheels on it. I can bearly read the part number. the last 5 digits are something like 80064. ?? does anyone know if these might be 15x7? Or those 15x 6 1/2 wonder wheels?? thanks
