...wouldn't the "C" designation he mentioned indicate the trans is at the earliest from 1969?...

Agree if it case is original but you know the way we all did in those cases back in the day and exchanged them for what ever we could find to fit.A true 66 M22 is a super rare piece. Be interesting to see what it had for a side cover and some of the casting numbers. That would help. Small output shaft is worth digging deeper.
