I have a couple brand new in the box King Cat or Mountain Cat 900 Driveshafts that have the 3.0 pitch drivers already pressed on ready to go. This was a kit that Arctic Cat offered to upgrade the 900 to the Attack 20 or similar track. They run about $200 for the shaft kit. Will sell for $75.00 plus freight. I have 6 available. PM me if you have questions.
