From what I've seen, people aren't "jumping" on you about asking, its the fact you have received the help and advice, but expecting others to do all the donkey work for you. Wishing parts just fall in your lap after asking several z based forums won't create many friends.. doing crap loads of research and maybe looking for actual pictures of what you need so then we know too what specific Z-L part you are after and also maybe the same as our Australian delivered models. I have only seen a few of the JDM Fairlady zed models here and I could see plenty of differences between the models.
If you are worried about sending credit card details online, grab a prepaid type card with a fixed low limit for international purchases... low risk just in case it does happen.
