1971 engine number location.

My March 1971 Fastback has the number stamped in the curve.
The location of the prefix and number moved rearward to the flat surface sometime in (mid ?) 1971 but by which number ?

20M3S / 143958

Well, it's rainy and boring today. I've noticed that sometime in the spring of 1971 that the engine case serial number moved from the front of the drive side case to the side. Just wondering when that occurred. Mine was built in May. So, it was prior to s/n 1483XX. It would also be interesting...

Somewhere around 145xxx but there's no known number when the stamps moved to the flat part of the case as far as I know.
