Dogbone and components are the same. Unless dogbone is u/s just change bearings and seals, from bearing supplier and if collars are needed (probably will be) availible from Honda. I note that the H&D one doesn't use the same bearings as OEM - should be full compliment needle rollers really. IMHO
Attached 4RT parts list (same No's as 315) Hope this helps.
PS don't forget the ones in the swinging arm!
