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 ( firstname.lastname@example.org
), 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!
