I threw a weight on my 911 primary 4 years ago and been borrowing a buddies stock primary. It took out spider and outer sleeve. I bought a new Yamaha OEM spider. Am I able to just buy a new Yamaha OEM outer sleeve for this clutch? I don't know anything about these 911's and how to find info or parts for them. It came the the Mtn Max when I bought her in 2002!
