A couple of weeks ago, I saw a second hand book in one of the local book stores over here. It featured a lot of diagrams, including the ones that were scanned and posted in the thread you mentioned (it seems like those scans were made from the book I mentioned).
If I remember well, the book also featured diagrams of the trailing edge flaps you're looking for...
So, maybe you should ask the person who made the original scans (maybe you already did, I don't know), or look somewhere on the Boeing site or so?
