Radiator Notes: 1963-67 aluminum radiators contain a Harrison identification tag, but the part number and date code of manufacture are stamped directly into the top left of the radiator. Radiator date codes consist of two digits representing the calendar year ("53" through "67"), followed by a letter representing the month ("A" for January, "B" for February and so on).
