Depending on how bad you want it, I have friends in Korea who might be willing to middle man it. It's weird offering that, but I got my friends wife to help me order some specialty parts from Japan. . Anything for the good thock!
You could also look for companies that do what tenso does in Japan - middleman ordering and shipping (for a fee), but some Korean language would probably be needed. Actually I work with like 10 Koreans, I could ask someone if they know of anything like that if you'd like.
