Welcome to AF!!!
Try ebay, like
Guiddy said, that's a good place to start.
Does your local hobby store carry any Fujimi models? If so, you could ask them if they can special-order anything from their suppliers.
Also, take a look at
www.hlj.com. They are a mail-order site, based in Japan, but they're really good.Their excellent prices offset the shipping costs.
Let us know if you find one!

Good luck!
