Thanks! Looks like AB code was only used in 1977, so "probably" numbers matching. I still can't find a decoding of the stampings that matches what I have here. Guessing K7 is Canada plant, 1977 and 117 is the day. But, the cowl tag build date is 3C (3rd week of March), so the 117 would be a few weeks after that????
