Thanks guys for the posts....it does appear that SDP did use a variety of ties over the various TD models (P80, P90, P93), but never really noted which was which.
Nigel, I'II remember that and endeavour to track down the Mercedes part number, (You've obviously got a friendly Merc dealer....I've tried a few here in the past for various bits and pieces and without a Part No: and/or VIN they didn't want to know me

) but Xavier on Robi's Forum pointed me to an Ebay site where I could purchase them (they list them as VW Part) so I ordered some......Admittedly you paid a lot less than I did from Ebay, but I did get a message earlier saying that they have already been dispatched.
Here is the Ebay site in case you need more and can't get the cheaper Merc one's
