Welcome aboard and sorry to hear about your accident. In Europe I'm not too sure about your options..., I would try to search for someone that imports american cars, and go from there maybe? Maybe a Ford dealership could help you too?
Not sure if they'll have the part you need, but I've heard
Ford Mustang Parts | Mustang Parts & Accessories | CJ Pony Parts do ship in Europe (never bought anything from them tho...)
http://www.norcalmotorsports.com/ who work with
http://www.sacramento-mustang.com/ will ship to Europe for sure, contact Jason Miller (
norcal@norcalmotorsports.com ), he will help you out.
Do a search in google as well, maybe a German Mustang Forum would be a better place to look. Good luck!
