Research Topics & Reports / Re: Gas tank date codes
« on: Today at 02:44:19 AM »
The gas tanks are dated with a week and year code.
67 has a calendar week code. 16 D 7 would be the 16th week of 67, day shift. 40 6N would be 40th week of 66, night shift.
The format changed in 68 and 69 to have the week counted from the beginning of the *model* year. The extended 69 model year used tanks dated for the 70 model year.
LOS and NOR data is intermixed and shows the same pattern.
