Here is a factory ECU and engine wiring harness for a 1977/1978 Datsun 280zx
I don't believe it is NOS but the condition is amazing - especially the wiring harness. Looks factory fresh.
Everything you see for only $200.
I have two NOS driver (left) side windows for the Datsun 620 and one used (but excellent condition) rear window for the 720.
All from an automotive glass shop.
Thanks for looking!
