Mario, Sounds like you need to remove your existing OZ wheel/sprocket/cush drive etc and take the 999 components to a machine shop and get them to machine the 999 components to fit the OZ stuff. OR Modify the 999 wheel to fit the OZ cush drive and get new spacers made. I would contact Sigma Sport (Tunbridge Wells area) and see if they can assist as they are experts in this type of stuff.
