I have changed a lot of clutches and never used new bolts. The correct torque, a drop of blue Loctite (if there are no mechanical keepers or tabs) and you should be good to go. Looks like the kit comes with a new TO bearing and an alignment tool....should be good. Clean all the surfaces with Brakleen or similar and have clean hands when you put everything back together...no grease on the flywheel or discs!
