I'm in florida... but I hear you on that! I feel the same way about my engine parts! Everyone carries a TON of parts for the SR20 (the newer Silvia motor) but I can't find anything for my CA18 (the older one). But I can get stuff on yahoo japan all day long for dirt cheap:(
here's a website you should check out...
http://www.rinkya.com they actually bid on yahoo japan stuff for you (in their name), pack it up, and ship it to the states (for a fee of course) but they can't do big body stuff (like bumpers). They can do trim, moulding, rear spoilers, and mirrors if you're interested in smaller stuff like that:) I plan on ordering some suspension and engine parts through them here shortly! The way their shipping and price set up is, it is quite a bit cheaper to order a bunch of things and have them sent as a package. Like get a spoiler, and they'll throw smaller things in the same box, and combine shipping.
