kz750 E2 parts interchangeable with other years/models?

I have some mics parts from my kz750 that I would like to know if they would fit other years 750s and or other kz likes 440, 900, etc...

Is there a website out there where I can just plug in a part # and see what all bikes it goes to?

Thanks guys!

Go to the owners area, access the parts diagram, plug in you VIN or model info then select the parts out of the diagram you want to check. Click the part number link and when the little window pops up click the yellow question mark. It will list the model and year of every machine that contains this part.
