Hi Collette,
I am sure Suzuki have stock, but since the new part number is priced at £400 I don't expect anyone will buy them!
I have used Impex,
https://en.impex-jp.com/parts/new/searc ... 5810-50E10 lists the parts they claim to be able to get. I went for the Pitwork one which appear to be a Nissan parts brand.
They seem to be ok and at about £46 including shipping much better value then Suzuki!
The carriage fee seems to include any import duties, or at least nothing additional was added for that.
