All looks really great so far, BIG Congrats!
Unless I missed something, what of stampings being you believe it's the original drivetrain?
Bummer the Vin falls within the NCRS missing info range but keep digging also long shot but may be worth trying on Canada Vintage Services too.
Bob's right on about searching heater ducts etc as clues may lead you close enough to someone who may remember it, who'd ever forget such a car?!
Pull the seats including backs also carpets, kick and door panels plus a good search up inside the dash area too.
Good luck!
