Alright, the plasma and electrical runs are in above the shuttlebay. They still have to be run forward; but, that should be (cough) cake next to what I've done so far. The next real problem.. well..
You can see the runs here from below with some minor mods to the pressurewall supports.
And another view from above. The forward portion of the lines still need a tweak to the angle up the spine; but, that's 2 seconds.
..here's the problem. The ribbing hasn't been booleaned to fit up to the hull structure of the nacelle yet; so the lines may or my not fit. Once cutout, there may be just enough room to squeek by; but, we'll see.
Back to work..
