Date code question
I have a vague recollection regarding an exception that was applied to the date code rules for the parts on our cars. Seems like I recall that the letter “I(eye)” was not used in order to prevent confusion with the number “1(one)” Following that logic a part dated 5M1.would have been made in 1965/December/first week. Is that correct?

1967 model year is the only year that didn't use " I " on engine castings - such as block heads intake.
Other parts like distributors alternators and what nots - never used " I " in any year model. Your date code should represent Dec 1 1965 ,,, or 1975 5M12 wouldn't be the 12th week , for example |

BVZ is correct.
The way to think of it is if stamped, they didn't use 'I', cast it was probably used.
