long time locking but still did not find some for my 2014 E350.
I'm searching for the rear door pop out windows including brackets.
Those have bin build by Ford from about 1992(??) until 1994.
The inner plastic frame is not necessary needed.
I am located in good old Germany in Berlin. But I will definitely pay for shipping + handling.
So if someone has got something to offer please get in contact with me.
