Hi,
by rebuilt, do you mean resealed, or did you do more than that? If so I would be interested to know how to rebuild a steering box which has some play that adjustments can't take care of anymore.
You need to make sure that the arm at the bottom is properly positioned on the splines. There are marks that need to align.
Then, with the bolt through the casing as you did, you must make sure that the marking on the steering column points to top. That marking is on the steering wheel side, right where the bolt goes.
If you need to access the coupling area with all the elements in place, you can do so from the foot well side by undoing the cover that holds the steering column to the firewall. You have nuts on the firewall, and a collar on the column side. You can then slide the cover upwards. But you may know that already.
