I'll start with just one recommendation. If your wife has trouble steering it with a manual box, if it ever quits with a power steering setup, she'll be in even deeper trouble than you may like. I'd recommend looking for some steering components with a shorter Pittman and idler arm to reduce the force necessary, and stick with the manual steering. Or a box that is even more turns lock to lock might be easier. You'll get the mechanical advantage, but will have to make more turns of the wheel to turn. If turning it is easy, who cares, right?
