Help me find a new fuel cap surround please !

[shortcut]

Hi folks, I had to drop the fuel ank out of van in the week to remove some unwin floor tracking and then to fit in a new tripple seat ( thankyo moggythaw ).

Now appart from the bolts that hold the fuel tank straps being a pig everything went swimminly with the job, but... the oval plastic surround/ infill bit complete with large foam washer didn't survive, I didn't think this would be a problem to replace so called into ford this morning and the nice man found what he was sure was the right part and said don't worry its only a tenner followed by ... we can't get hold of them anymore !

What now ? I havn't yet found anyone who can successfully remove one without breaking it and if I can't buy one new i guess i'm screwed huh !

anyone have one spare, or can anyone houdini a second hand out of a scrapper for me..

The reg for my van is M846BLN which I think makes it a mk5.

many thanks
