KZ305 Ignition Coils

Hey guys I need a new set of Coils for my 1981 KZ305 CSR. I can't find any exact ones on ebay so I was wondering if anyone knows of any other coils that would work as a good substitute. I was specifically wondering about any of the Ninja 250 coils, as there is a ton of them on ebay for cheap.

Any advice or help would be much appreciated.

Thanks alot.
