Hi all. I have some questions about BJ42 LX's. I have been looking everywhere but can't find a concrete answer. Does every LX have 3 wiper blades or did some come with 2? I keep seeing pictures of people posting BJ42 LX's with only 2 blades and I am wondering if they are legit. Also were the sliding rear windows an option on the standard BJ42 because I have seen those on some "LX" models with only 2 blades. Thanks for the help!
