If I could get my hands on an old paint kit I might be able to make a CF-BAU for you from scratch. I thought about cutting/pasting from Grant MacLean's textures onto existing "sw_p51d_..." textures but I can't open some of the bitmaps with my version of Photoshop.
I've handled this roadblock before, though, and coincidently with a P-51D model that went through model rebuilds that also changed the .bmp texture layouts. In that particular case it was for the game Jane's WWII Fighters
by Electronic Arts. As I recall, I was able to convert bitmaps to JPEGs in Microsoft Paint, open them up in Photoshop to edit them, and then resave the finished work to bitmaps in PhotoShop. I may play around with that later this weekend and see what kind of a Frankenstein monster I can build for you.
