I did not need it after all. Upon inspection by an experienced Jag mechanic, the box in my Jag was sound after all, so I don't need this box.
We did not need to open it, but we had it cleaned. It was removed from a salvage 120, so it has probably never been opened. The steering column has been cut with a torch for removal (see photo). I have no reason to believe this steering box is not sound. This item is in the category "Collectibles\Transportation\Automobilia\Patches".
