742 case setup help

I went by what a member here did with there 742 case. He had talked to cass (dr. Diff) and was told the 10 spline pinion should be torqued to 170 ft.lbs not the 240 that's in the service manual. Also should be between 15-25 in.lbs rotation torque without seal in and a couple more inch lbs with seal in.
