And as mention before its a 180sx type-x aero also know as 180sx KOUKI, you probably seen the tail lights (kouki tails) all the hatch guys go nuts over, well their from that car. 180sx came as Zenki(89-91), Chuki(92-95), and Kouki (96-97) which is late model, chuki being mid, and Zenki being early model.I might be off with the years but you get the idea.
