I've Googled til' I'm blue in the face...

Does anyone, anywhere know where I can purchase a T-13009 boring bar holder for an ancient Mori-Seiki SL-4? This is a cast holder with setscrews in the side and a 1 3/4" bore. One of our machinists had a boo-boo (of course no one knows what happened, as usual) and I need to replace my back-up holder. I've been here over 30 years and have never had to replace one. Just happened to find a backup stored in a cavity under the machine! I need one in case those invisible gremlins return.
