I have a Grace. Hmm, weren't these imported by Sumiko? You might try calling them. http://www.sumikoaudio.net/ Here is the website, contacting them wouldn't hurt.
Grace went out of business, which is such a shame. The current Grace company is a Chinese manufacturer I believe who picked up the Grace name, so they will be of no help.
Good luck.
