Yep it's an S31 Fairlady Z 2.0ltr (L20A) motor, early S30Z tail lamps, G-nose assembly, flares etc.. somehow I very much doubt a 1 owner example. The Niles clock was indeed a later clock. 74 models (Z-L's) still got the twin knob rally clock, it was 75 they got the Citizen single knob clock, then 76/77 they got the Niles clock. This 1 has factory fitted fuel injection.
Totally disingenuous description..
