Sorry to hear about that steering box. 
You can go ahead and put the shaft and pitman in that box andmock up your steering box, plus it will be lighter, and mabye easier to move around while you figure out the perfect placement. You will of course need that front axle under there in order to get everything parallel.
Good idea
I'll use it for steering mock up!
Did you get your shackle tube holes cut out of the frame as well?
Huh?
I've got an 85. I'm just gettin' a little beef and lift out of the new hanger
