Verson 4 with bomex lip
SOA does not carry it anymore, and otherwise it is hard to get. No matter what shipping will be the biggest pain since no one in the US can get it for CHEAP and little shipping.
Someone is selling one on the private for sale now, but other than that, you could try some of the NASIOC vendors.
BTW, youll also need to buy the JDM lightweight bumper beam for it to fit, unless you REALLY want to modify your stock beam.
