CH47 Texture Painting Question

Hi - I'm absolutely loving the CH47, you've done a great job already and I'm looking forward to the impending update, and SU15 flight model changes.

I'm working on a custom livery using the paintkit, but I can't find out where the texture images are for the black emergency cut squares around the windows. I want to change these to yellow for my livery, similar to the yellow markings on this example:

I assume there is another DDS file somewhere in the "texture" folder which is not in the paintkit, that is used for decals like these. Can anyone from Miltech point me in the right direction?
