914 6 chassis numbers are stamped into the center of the rear trunk floor in front of
the latch receiver.
I do mention the center location on early cars (not just /6s), i'll add your pic for reference.
I also mention that the Karmann plate only has a chassis number for /4 cars but maybe i should make this more clear and explicitly state that the /6 cars do not have it on the plate.
