Teddy, as a mere PPL-I peasant with some image-manipulation capabilities, I'll take my chances...
I agree that it is difficult to find much detail to scale by. This is my best effort to scale and align the debris at the three positions I could find.

The image shows the debris overlayed on the image with 35% opacity to make it possible to "see through" the overlay. The alignment is purely visual and 2D and does NOT compensate for the foreshortening in the EK image. However, in my mind it suggests that the most likely location of these three is the most inboard.
Will post follow-up with zoom.
Keep that flak coming...
