so where you getting your info from? sorry for my sarcasm. i think i know what you are talkn about from ns.com. a few places imported them from US cheap as the OZ dollar increased and ppl were virtually getting them at abargainn price including delivery. the real ones are forged and jap made. i heard some taiwan copies were getting around- not sure though.
so you mean you worked with origin-lab D1 parts manufacturers, that work with 7 tune, hellaflush etc in the US??
