Is the part number the only way to verify them from other 15"x7" wheels or do they have cosmetic differences?
The part number 2944450 is the easiest, but it is not on early wheels. As posted it is a stepped down 15" ring on a 14" center. The date should be stamped next to the valve stem. Also the pentastar.
The ring should be marked 15x7 J and should also have a date.
