Do not get the rear blade on a 24+ Hyundai(?) If you get any aftermarket blade be prepared to break part of the arm or do what I ended up doing. That arrow points to the bit that will block aftermarket blades on the newest Hyundai's. I think they did that on purpose.
I took the rubber portion and two metal strips off the scrubblade blade and moved it to the Hyundai OEM wiper. Why? Hyundai stock blades; front and back - are terrible. Almost dangerously bad. Get new blades and see the difference.. even new vs new blades. Moving it wasn't easy and voided any sort of warranty it had instantly. It is working - far better now. I can see behind me again!
Great blade but it doesn't fit the new stuff from the Korean manufacturer. Lengthwise - perfect. I might end up using a better tool to get that aftermarket blocking bit off the arm - but for now, I am good.
