Ortofon SPU Meister Silver MKII like cartridge to fit a Kuzma tonearm

Ortofon Royal N can fit, that's the only Ortofon SPU without headshell. 
But you'd better try Miyajima Kansui 

I loved my Royal G mkII with Replicant-100 stylus profile. 
I also enjoyed SPU Spirit (limited edition model) with Elliptical profile, my sample was number 500 (and only 500 were made).  

Miyajima is much more interesting low compliance cartridge than SPU, mainly because of the unique cross coil method (Miyajima patent). The Miyajima is the most organic MC cartridge I have ever heard! Highly recommended.  

very strange, modern ZYX Airy III and Premium 4D were both completely different from any Ortofon SPU (I owned 3 different models) in my system. ZYX was a high resolution cartridge with MicroRidge profile while the SPU is not a high resolution cartridge with its Conical or Elliptical tip (exceept for the Royal GM with Replicant 100 stylus which is a high resolution).
