HiMold is the resin subsidiary of PitRoad models of Japan.

Although I didn't see any HiMold kits listed on Bill Gruner's Pacific Front Hobbies site
http://www.pacificfront.com/
I know he has carried them in the past. Contact Bill directly and ask. Call - don't email. Bill is very good, honest, knowledgeable, and responsive on the phone but he is often too busy to promptly answer email enquiries. If he doesn't have what you need - he can order it or tell you who may be able to get it.
Another option may be Hobby Link Japan
