The rear quarter emblems? I think it is just a matter of the original (vented) quarter emblems being switched to the earlier Export type '240Z' emblems after the original holes were filled in. Builder decision, I think. I don't think it's a symptom of shell-swapping...
I sold the (Japanese aftermarket replica) 5-piece Grande nose kit and (original Nissan) headlamp covers to the builder/owner Alan Edney back in the late 1990s. Pretty sure I sold him the MK63 four-pot front calipers too. He found the basket wire wheels at one of the Billing Aquadrome meets I seem to remember...
Not everyone's cup of tea (and certainly not mine) but I believe there's a good, straight and solid car underneath all the add-ons. Could easily be made into something a lot more appealing.
