Can anyone help decode this? My searches are coming up empty... Reads: 03 1 66 N2 9783404 (S) 51 Guessing the first set is the date, with N2 being night shift? Confused on the lower set, shouldnt there be a 4 for Buick motor division? Any help greatly appreciated
The 9783404 is the stamped ID for the boxed frame used on the GS/Convt. for 1966 & 67. 03 1 66 = Mar. 1, 1966 so it could be for either year. S = A.O. Smith, manufacturing source. and you already know second shift.
