ZZR 600 crash knobs

Hi I am a newbie and this is my first post:
Does anyone know where I can get a set of crash knobs for a 2004 ZZR600?
I notice some bike models are advertised as no-cut, but I,ve been told these are inferior on some bikes such as mine as they are only mounted to the sub-frame. And may do more damage than good in the case of a serious slide.
Who's got the clues? Cheers Marty.
I am currently in the process of putting a ZZR 250 motor from a 2006 model into my son's 1990 model.
My second post will probably be tomorrow if it doesn't fire.
