If I were you I'd reassemble as much as possible. Console, wiring, interior, headlamps, panels, wipers, bumpers etc. The more complete it looks the better.
Take lots more photos from all sides, inside including hatch and spare wheel area, and underneath, and with all the plastic sheeting removed from the engine bay so people can actually see condition and where the project has stalled. Presentation is everything, first impressions really count.
Better yet if you can finish off the motor with exhaust etc and get it running.
What happened to the original L26 motor & gearbox? Is the project reversible back to originality? Not every Z fan would want a modified car.
Best.
