If you can't find a source, as I suspect you might not, consider having
a shop wire EDM it out for you.
Someone should chime in with a source for a Cad program to create the
profile file.
Finding one ready made seems doubtful, having one custom cut will be
wickedly expensive, EDM might be the way to go.
