You can try the stores listed on this site. Upright King bells are fortunately a lot more common than upright Conn 2XJ bells. The other place to call is 1-800-USA-band (Taylor Music). They take quite a few horns in trade and often seem to have junkers from which one might find parts.

Sam Gnagey was advertising some back in September. He might still have one. Try the link below to see his post. You should be able to contact him through is email address on the bottom of this post.
