BBD carburator rebuild - help needed

I am about to rebuild an 1969 BBD carburator 4608S. Following problem accured: when removing the Venturi cluster cover, I found out that the two needle style brass pick up tubes were loose and I don't know if they were even in the right position. I attached a picture of the way they came out (on the two inner holes) and another possible option (parts clean), where they would also fit (outer holes). They have a tight fit on the outer holes but are loose in the inner holes. Maybe someone of you has a reference picture of this cluster cover. There are plenty of pictures of later BBD carbs out there, but I could not find one of this particular carb. The only picture in the service manual showing the Venturi is blurry/to dark.
Thanks Wolfgang
