Zentraedi ship reference needed!

[chrono]

Ok as some of you already know I'm working on a medium quality 3D model of the Zentraedi(yes I know that name it's the 'true' name) Picket ship. I'm current at the point in model building that I'm wokring out the details. However using the information I've found if tricky.

Right now I know where all the 'main' and secondary engines are at except for one of them. It's said to be placed on the 'dorsal side facing aft'. However I don't have any images showing exactly where! But I 'know' it's either just above the rear hanger or the cone-like affair on the ships top.

So what I'm looking for is any views showing the ship from behind and above.
