How difficult is to replace a broken cantilever?

Have an old MC cartridge that was given to me. Clearaudio "Goldmund" made in W. Germany on it # 610235. There is not needle/ cantilever/ stylus. All I see is an empty hole where it once was. How difficult can this repair be for someone who has access to an electronics repair mans bench? Where can one get a stylus part? Has anyone ever done this on their own? Curious.
That is a job for a professional retipper, Soundsmith for example.

Ditto on Soundsmith. They just retipped my Benz for me but they also do the whole cantilever too if necessary/possible assuming there is no internal damage they can't handle on the "motor".
