My wipers are getting on abit so i have decided to change them. But it doesnt say in the owners guide what size the blades are so i measured them on my car. the passenger side was 19" and the drivers side was 22", they seem to fit perfectly. i then went on ebay and noticed that packs of wipers for bravos were labelled as 20" and 22" or 20" and 23". which 1 is the correct size? this is really annoying. some one shed some light on this matter thanks
