I have an F2 but I need new fairings and I don't really like the square headlight look. I see a lot of articles about using fairings and the headlight assembly from an F4 or F4i (these might be the same, not sure), but I don't know a lot about these and haven't really tore mine apart, just because I don't know when I can ever finish. Does anyone know of a good how to article on this or give me a step by step? thanks much.
