I would like a spare set of wipers in the shed. From the dealer in Aus the cost is A$130 part # A2048200845 or A2048200245 ( on wiper) I see OEM wipers from Autohaus.com in the US for US $20.05 part #2048200145 or #2048200745 at dealer. Would anyone know whether RHD/LHD wipers are interchangable for the 204 C Class & where is a good place to buy them on line?. Thanking you. Carsie.
