Gearbox codes.

[Tucson]

Hi All, Just popped over from the Mustang Forum to ask an Escort question;- I have a 1970's 711M 1600 Escort? motor and gearbox, the gearbox has the following build tag on it, 75 AA AA, & below on the second line FNZ 6 F 24.

Can somebody please decipher this for me. I was thinking the FNZ has something to do with Ford New Zealand, bot maybe that is too obvious. All assistance would be greatly appreciated, Thank you.
