BTW, I have 418A as the rear wiper, but it probably doesn't matter for the rear to use 418A or 418B.

Basically the rear wiper is about 18" long and I'm just wondering if the A vs. B is the shape of the connector....or if the "B" type wiper is a little more flexible (I noticed in most BMW front wiper application, the "A" type wiper is for the driver's side & the "B" type wiper is for the passenger side).
