Where to find OEM S-tune parts?

[playRR]

Well I sold my entire Nismo Kit. Managed to snag an OEM base model front and rear bumper in my color too! Theres no going back now that my car is officially a base model swapped nismo. I managed to snag a set of rear spats AND the mustache too! But I've run into another roadblock

I downloaded a nismo catalouge but it is only for japanese customers. Upon typing the jdm serialized S-tune aero parts into ebay or facebook I'm met with nothing (since they dont have ebay from what im told). anyone know the part numbers for the S-tune aero here in the states (if theyre different)? Are the parts just so hated that people toss them without considering selling them?

Im looking for:
Front lip
Sideskirts
Rear deck lid

P.S. I know Z1 sells a majority of those parts. But I managed to snag the mustache and spats for under $300 so Im definantly NOT spending $2000 for the rest of the kit. Especially if it would have costed me $500 for just the rear spats
