Box at end of steering column

Hello Everybody,
Silly question time. As per the pictures can someone please tell me what the box at the end of this steering column is called? Are there rubber seals or rebuild kits available for them? If you know of a thread where this has been discussed previously please point me in the right direction. This is for my 68 Plymouth Valiant which has a column shift. Thanks for your help.
