Here is the cab, underframe and engine textures all naked.. Essentially just the alpha channel cleaned up to remove all the artifacts and removing some sections that blocked other items and all adjusted to be same overall brightness. Under base I left three areas as is as they usually require no actual paint.
These are the same templates I created and based all my GP9 repaints off of so figured I'd toss them out here for anyone who wants them.
