Little update on this...
1) Many thanks to Julian Best for sending me a copy of an old Invoice for the parts I was trying to source, with (of course) the suppliers name etc on it.
2) The reason that I didn’t use Julian’s details is because yesterday afternoon I found a UK supplier with both parts on the shelf. After having paid early this morning, they are now both on their way to my work address (in case we and Mrs Mc go out for the day), with delivery expected tomorrow.
So big thanks go to: Sussex Auto Parts Ltd and in particular, Matt for his excellent service!
