I put a Touran rear wiper on my LC a fortnight ago - it looks damn good. It wipes and looks a hell of a lot better than the standard one it replaced.
All it needed was a slight trim to the cap (integral with the arm part) as there was contact with the rear windscreen during the wipe, but this was a case of 2 millimetres shaved off the bottom edge with a craft knife, and not all round the cap.
