Rotor exchangeability

So, my rotor magnets cracked and came loose when I tried to take apart the rotor to check the starter clutch so I guess I have to buy a new one..
But what model and year rotors will fit my KZ1000R -83?

According to Kawasaki.com these 37 models share the same rotor (21007-1036), shouldn't be hard to find:
