Datsun 510 sss Seat option, original or aftermarket?

[Labubre]

Hi,

As a reminder.

Got a '70 510 sss from Portugal

No car history available so i ask

Got these head rest thing that i can install from above seat without anything pluging in...i mean like a socket

With a pocket for the rear passenger.

 

Even seen that???

Looks like an aftermarket option, can't say for sure but doesn't look like a Nissan product to me.  But still, unique and probably rare, nice addition to the car.

In N Am seems the '68 did have an optional front bucket seat head rests but it's not clear how they were attached. Head rests on posts appear to be standard equipment on the '69 and up model year bucket seats.
