Fisher Body Assembly Date The date is coded as a 1- or 2-digit month and a single letter week. Some plants would pad a single digit month with a leading zero (0), some did not.
Week Letter A through E The week letter typically ranges from A to D and an occasional week letter E has been found. The letter "A" is the first week, the letter "B" is the second week, etc. However, there is not a direct correlation between a week letter and specific days or a physical week of any given month and each plant seemed to have their own standard operating procedures explaining why some plants for a given month may have the letter "E" for a fifth week when other plants do not for that month. |
