I have been enjoying my aero for a few months now and am thinking about replacing the little wipers for the headlights. i havent really missed them and have been thinking they may be more trouble than they are worth. has anyone ever done this? they are completely missing, the whole assembly that is, with only the peg sticking out from under the light. seems like a piece that could be interchanged through out the 9000 models. I am also still looking for a good manual for american 9k aero that may help me out. opinions/help would both be appreciated.
