? Source for mirror mount

[2004Tiger]

My 2004 kitty fell over in my garage (don't ask) and broke a part. I need the mirror stem fitting which is the interface between handlebars and the mirror stem. This piece has a 22mm hex between a large upper thread and a smaller bottom thread. The smaller thread/stud broke off, thus saving my mirror from breaking. I think I saw mentioned here some time ago that a Jap bike mirror assembly is the same, but after wasting lots of time in searching, I can't find the post. Is it Kawasaki? If anyone knows what fits, please tell me.
