Serial plate: Transmission, front upper-right corner, stamped into the top of the casting

Two published sources broadly agree on these year breaks.

US-built serials start with C; A = Belgium, B = England. Ford plates from 1965 on carry a production date code such as 5L29C: the first digit is the last digit of the year (5 = 1965 or 1975, the serial table tells you which decade), the letter is the month (A = January through M = December, I is skipped), the two digits are the day, and the last letter is the shift.

One published table. Treat the year as approximate.

Single source. From 1987 serials switch to BA / BB / BC prefixes (1987: BA80100, 1988: BB06622, 1989: BB80620, 1990: BC26239). Ford plates from 1965 on carry a production date code such as 5L29C: the first digit is the last digit of the year (5 = 1965 or 1975, the serial table tells you which decade), the letter is the month (A = January through M = December, I is skipped), the two digits are the day, and the last letter is the shift.
