I am not 100% on this one .........................
I have a 2003 factory service manual that I use as a referance for my 05KK. It has worked really good for me, but I would verify the really technical stuff. I am thinking that KK's are the same as 900MC's in 03'. The manual says center-center should be 30.9mm or 12.200". The ofset is 34.67mm or 1.365". I hpoe somone can chime in and verify this. Good luck-00's
