The steering box isn't that hard to adjust. A spring scale and little bit of math for the torque spec. Too expensive to buy a low in-lb torque wrench for just steering boxes.
For the spanner, you can buy or borrow one. Or. You can make something using some bolts as the pins. That's what I did. Afterwords I bought the pin spanner since they do seem to come in handy now and then.
