Thorens TD145

I have a Shure V15 that now plays only 1 channel of a stereo LP, so I'm guessing that the cartridge is failing. Checked and moved all connections to confirm that the problem is not associated with the tuner or speaker connections. If this is a symptom of a failed cartridge, what are some newer cartridge options? I'm considering a Shure M97? But will it fit, etc.

Thanks
