Editing ship orientation in persistent file

[Deadweasel]

Hey all, I'm trying to correct a ridiculous oversight by swapping out one version of a deployed vessel for the fixed version, sitting on the launch pad.

The difference between the two is that the fixed one's root part (a standard docking port) is intact as the ship sits on the launchpad, whereas it was knocked off from the deployed one as it landed.

As a result, when I swap out the definitions in the persistent file, the "new" deployed vessel is now completely upside-down, which results in some nice fireworks once physics kicks in.

I'm pretty sure I can fix this fairly easily by flipping the root part or the ship itself over, but I'm not sure what the values should be in order to achieve this. The root part's (partial) config looks like this:

PART
   {
      name = dockingPort2
      uid = 2786357868
      mid = 1455513462
      parent = 0
      position = 0,0,0
[B]      rotation = 0,0,0,1[/B]
      mirror = 1,1,1
*-snip-*

Meanwhile, the ship itself has

rot = 0.4343523,0.723475,-0.536573,0.00338749

The thing is, I don't know what min/max values should be, or which value to even change. I've tried using 180 on a couple of the ship's values, but they just set it sideways.
