After.

Also, It seems I was wrong. The modded arcs are displayed on the purchase ship screen, but after buying the ship they revert back to their original settings.

The modding manuel references the xfile,

"The starting weapon arc in degrees. This value should match up to the weapon arc degrees in the spaceObject_Xfiles file for this firing point. The arcs should be in 22.5 degree increments for proper display."

I guess in this case it means the Xfile, "abbidon_cruiser1" if so I don't understand this file enough to make the required changes. It just looks to me like it is just building the model for the ship.
