Can anyone shed some light on this 2944169 H wheel. Appears to be dated 2 22 71 (M51) next to valve stem. Would this be a service part? Or, did Mopar use these in production after 1969? What is the estimated value of a single wheel dated 71 versus the more desirable 68-69 dates.? H is visible on front side. Just filled in with a couple coats of paint.
