Any good Kawasaki dealer should be able to help. Kawasaki Motors furnishes it's dealers (at least they used to) with parts interchangeability information. It takes a single part number and resolves it to the model or models that the part number is applicable to. And to answer your question, sorry I don't know if any other rad's will fit. As bad as it sounds....just save up and buy new ones. I have two bikes that I have tried to buy used ones for and all attempts have ended miserably. As far as repair.....I couldn't get the one place that was recommended to me to respond to an email so I figured that was an indication of their overall customer service, so I passed. Hope this helps somewhat.
