I built this 9" center for my Raunch Wagon with a new Richmond 3.89 gear. I wanted more so I built a 4.11 for it and this one has set in a bucket since. New Timken bearings, new Richmond gear set, new aftermarket Daytona pinion support, new billet 1350 yoke, used Detroit Locker w/28 spline axles, and setup with shimmed pinion preload. Maybe 150 miles on it. Pickup in Adrian MI. $650 OBO
