Hi Mike
Happy to split these and your offer is accepted for the bars only. They fit the XC60 and they are indeed lockable, they were put on once onto my 2016MY XC60 and fit very well.
I live in Anstey (North Leicester) and my email address is
sa.fleming@ntlworld.com if you are interested and wanted to drop over to collect them sometime?
Cheers and very best wishes,
Doc
