ASL for IXEG Boeing 737-300 1.1

Are the wing and engine textures ok for all liveries and where do I install them please.

There is the instructions.txt together. After If you check the file you will understand and see the logic and probably you can use the wing file for other repaints as they have more or less the same "gray" color, but i do not recomend the engine file because it is in blue color
