Ignition lock

The clamp on my ignition lock has snapped (god knows how) it’s a Lucas 162sa I have looked about on paddocks but I’m unable to tell which one I need. I guesss the part numbers have changed or I’m missing something. Would like to replace the whole unit as I can remove my key whilst the engines running so it’s a bit worn out and not great for security.

Cheers in advance

You'll have to put up year etc. to get a bit of help.
Found this one, it'll get you started!.....
