which forks/swingarm best for kz650?

I know i know i could have searched,and this is probably the 1,000,000'th this has been asked but....

found a zxr750 L1 up for breaking,thinking about having swingarm/forks/wheels and brakes...sound like a good idea,or is another model (or marque) a better bet?

which is the commonest donor for a z650 swingarm/fork swap?

thanks all

you can make just about any sport bike suspension work
