Early 240Z Fiberglass Sugar scoop headlight cones

Hi all,

Does anyone have any idea of when the Australian 240Z's changed from the fiberglass Sugar scoops to the steel ones?

*Official* (according to the Factory literature) cut-off from FRP to steel was June 1972. It was a switch from E4100 (FRP) suffixed part number to N3000 (Steel) suffixed part number.

In reality, there were quite a number of cars which left the production line with one FRP type and one Steel before that.

I've been told that the main problem - and the reason the 'Sugar Scoop' headlamp housings were initially made from FRP in the first place - was that Nissan had problems in perfecting the press tooling that would enable them to knock out thousands of steel housings reliably. Their complex shape and the sharp details that were part of that design required some delicate tooling shapes which were too easily damaged when they tried to ramp up production. Repairs, re-design and - eventually - subtle changes to the shape (less sharp detail) finally allowed them to go into full production with the steel versions. It took a while, evidently...
