Sounds like it will be a 280ZX, the model no is S130 or something like that. No body panels are interchangeable with the earlierZs. I think they changed to that model in 1978, so there is a small chance that it could be an HS30 280Z (without the X) but these were never sold new in NZ. My Z is a 1975 280Z from California. The front valance panels are different from the 240Z. If by chance it is the early model you're looking at I need a few parts, I'm in the NI. If you're keen to onsell some bits let me know.
