Ford AOD Transmission Metal Assembly Tag

[1974truck]

I have been trying to decipher the Ford assembly code on this project AOD Transmission with little luck. I started with local Ford dealers, local and on-line Tranny shops, Ford and Motorcraft Customer Sevice in Dearborn, suppliers of transmission parts, and on-line tech help, as well as, my tranny repair manual. None of which could decipher the codes on the metal tranny tag.

The tag reads as follows:

PKA FA2

FOVP AA

Any help would be greatly appreciated.
