i have a cb 550 k3 which has been made up from different parts it has what i think is a swing arm from an f i am trying to make it as correct as possible, the problem i have is i have bought a swing arm which was described as a k3 when i build it up the axle bolt is too short to get the nut on far enough to fit split pin, i have got the correct spacer which appears to be the only difference i was wondering if anyone had a k3 axle bolt they could measure for me thanks
