The automotive "Model Year" (MY) is different from the calendar year.
1971 MY would've run from August 1970 to July 1971, & similarly for other MYs.
So the delivery date would be shortly after that - earlier in Germany (West G. back then) & Europe, & later in the USA & other overseas locations to account for shipping.
My own 73 2.0 was built on 8/31/72 & first registered in California on 11/6/72.
I would guess that you'll find an August or September 1970 build date, if you translate your 914's Chassis Number, which is on the Karmann Plate on the left/driver side front door jamb & stamped in the floor of the rear trunk near the rear wall.
Chassis Nr. Decoder:
9(X) would usually be 95 for Karmann Plant, with 96 or 97 adding 100 or 200 to the number produced that day of the following XXX sequence (i.e.: 95 + 1 or 95 + 2).
Cheers!
