I quite fed up with the wipers and washers on the Model S - there is always a place on the screen that does not get any washerfluid - and overspray is enourmous. (Yes they have been adjusted several times). Therefore; I'm considering fitting the model S with the sprinklers from the model 3. So I need all the data I can gather from how the system is put together. The little shiled with the three nozzles in -is that replaceable - or is it an integral part of the wiper arms? How long are the wiper arms on the model 3 (not the actual wipers, but the arm from the motor). ..if anybody have some high res pictures that would be even better..
