Hi SAAC-
1969 GT500- looking carefully over transmission (in car), so not seeing any potential VIN on top. Has correct PGB AF1 tag. Case cast on 3/3/69, about 2 months before the assembly date of the car. Case casting is RF C8AP 7006, my questions is on that "car line" letter, the "A", which to my understanding typically meant the transmission was made for an unspecified Ford product, and that transmissions cast for Mustangs typically have a "Z" car line casting. I seem to recall that this is not a hard and fast rule however, I can't recall for sure. What say you?
Thanks in advance!
