Shifting problem with 833

Thanks ACE !
I'm on my way to the Auto parts store now. I keep swapping the pinion yoke and installing a new seal on all these different ratio 9" Ford Lincoln rear hog heads. What a pain finding the rear disk hoses..still no luck. I didn't put this rear in...I bought it that way. Now I'm worred about the torque on the pinion nut when I re install....I guess an impack wrench is out of the question? Anyone else go to 9" Ford Rears and know the torque setting? Thanks ! Bud
