I can (as a Dutchie) tell some more about those odd things on the front bumper..
My first resto of a 240z was in 1991, by then the cars were 20 years old and i could still get all the original parts at my local dealer, after a while i was like a employee at the Nisssan dealer and could order all the parts i wanted myself on the microfiche system (remember computers were not used for the early car types.)
I bought then many new 240z parts also the front blinkers, they came in beautiful chrome, and.. are on my 240z till this day!
The reason for them was the Dutch RDW (sort of DMV) sayd in their regulations that blinkers on cars for the Dutch roads should have them on a sertain hight. The blinkers were standard under the bumper on a "regular" 240z and that was to low!
So my first Dutch 240z had them on the bumper for that reason.
As i then restored a 240z in 2000 the regulations were still the same and i had to change the blinkers of my USA model 240z to blinkers on the bumper.. Since about 10 years those rules are made more liberal so the American cars no longer need the blinker mod.
Something else.. I got some rear lights from a car out of France, and... they have no lights for reversing! As we know a euro version has red white and orange lights/reflectors, but this set out of France is only red and orange !! Has any one seen these before? Are there more country's that have 'em?
Maybe it was an early version type i don't know, i only know i've never seen them! (They came with a whole load of other parts i once bought from a Belgian guy and he had it from a Frenchman.)
Could not find a pic of them so these should do.. imagine the white part is also orange! Thats what i got from France..
A extra picture of a Dutch 240z with our famous soccer player Johan..
Translation: Johan Cruyff: also fast on the road!
(It's a nice picture, just wanted to say i HATE soccer.. so i know the man but i really do not care..haha)
