Not Much, but it's all I've got. 28 spline pinion shaft on a g-force 9" rear end. Five hundred more RPM than planned and didn't exactly roll into the launch. Well prepped track in Houston. Since replaced with a Mark Williams 35 spline pro gear third member. The difference in the pinion and pinion support areas is noticeable. Rebuilding the 28 spline for
a 1/2 mile and mile set with a 3.0 ring and pinion
