Nut: Steering One lol

[Pug_XUD_KeenAmateur]

Quickie: someone tell me the size of the steering wheel nut on my 405 so's I can buy a socket of the right size

And do I need a deep one?

Thanks

PS; any tips on successfully re-fitting the speedo cable to the back of the speedo itself also gladly received

I can't remember the steering nut size, something tells me its 16mm but I'm not certain sorry.

The speedo cable can be a right £$"£$"£ the factory used an elastic band if I remember correctly to fit it in place. Not really sure of a sensible tip to do it. I've never done one.
