Thanks John.
The car was a UK delivered car, and the differences you noted were for the UK market. It was first registered in 1974 and thats where the confusion comes with the dates.
To put the calibre of cars into perspective. The three finalists for "Restoration of the Year" were a Ferrari Dino, Mercedes 190SL and a Holden Monaro GTS. The Monaro won in the end. The standards of restorations and the size of chequebooks is really out of this world. I was speaking to one of the contestants, and his restoration alone cost $200k!
Anyway, I am proud that the 240Z made it that far, and happy with the exposure.
