When I went through this a couple of years ago, I had the entire clutch assembly replaced. Had 86,000 miles at the time & didn't want to have it torn down again for something that could have been taken care of the first time. But that's just me. Heck, at 92,000 miles, my splines were like new but I'm so paranoid that I want to take the rear wheel off after every ride just to make sure all is still ok.
