KZ650 fork length

I have searched and searched an I can't find it anywhere. Z1E has the inner fork tubes listed for z1, kz900, kz1000 so I assume KZ650 are different, can someone tell me the fork length for the KZ650's? also if someone knows the 650 length vs. 900 length?

I'm not aware of any Kawasaki documentation that shows fork lengths, BUT keep in mind that the various KZ650 models used very different forks, so it would be best to identify exactly which year and model KZ650 forks you are trying to locate. Ed

I should have known that I needed to be more specific- 1978 KZ650 B2 forks. I have a 1976 KZ900 with badly pitted inner fork tubes, looking for a suitable replacement without breaking the bank.
