AI is incorrect.

FA - pick code for assembly line worker printed on the build sheet
IF - tank code on driver side
CV - tank code on passenger side

In between the C and V is the month and year ID.
In the picture of my '74 radiator is G (July) 3 (1973). And part number is on the top instead of the bottom (3030109, can't see the year ID).

Your picture shows A (January), can't read year.
