From my observations, cars delivered to non-USA markets from about 1973 to 1975 (i.e. late 240Z's and some 260Z's) had their front blinkers in separate housings, mounted ABOVE the front bumper. The front bumper did not have overriders - possibly to maximisie the angle from which these blinkers could be seen.
Datsun UK Ltd ( a concessionaire ) were so cheap that they simply used the Datsun Netherlands photo shoot car for the UK market brochure:
But apart from the door mirrors ( and the fact that this is an LHD car instead of an RHD car... ) pretty much most of the UK market cars looked like the above 'Euro' spec car. The front indicators were deleted from the corner valances ( special press tooling was made ) and moved up to the top of the front bumper, and front sidelights were incorporated into the headlamp units. All this done to meet new European standards on lighting ( height and function ).
Note the front and rear spoilers, which were standard equipment on all 'Euro' and UK market cars.
Note that Australian (and NZ?) cars retained the 'corner lights' under the bumper as sidelights/parking lights.
I have also seen photos, and owners stating that their cars have the blinkers mounted BELOW the bumper, like this -
My hypothesis is that all such cars had them mounted above the bumper originally - but some owners have chosen to relocate them below the bumper, because they prefer the look.
Has anyone ever seen an original sales photo or road test with the blinkers below the bumper to disprove my theory?
