You overtook me, man...:)

As I can see it on your screenies the J58 engine house is too short. It should strain longer at the half of the pink section (flaps). See SKFs shots especially that BB underview.
And some more high res. photos from DFRC, visible your 'requested area' :)(but not only;))>
I hope these photos may help you too, which I selected from the DFRC collection. 'cause the are a bunch of them over there. :)
