Is the problem with the crank handle stem, or the hole in the operator where it installs? If it's the handle, then see our 39-226 . However if it's the operator, then you will need an all new operator, since they don't make them like that anymore. We can help replace it, but I'd need to see yours out of the window.

Perfect, thank you! I made a list of hardware on the right side of this page. I think you'll find that they match what you have quite well. Let me know what you think.
