Thank you very much for viewing this item. I intended to use this on my Prius (50 series, pre-facelift), but I replaced the entire arm, so I no longer need it and am putting it up for sale. This allows you to convert from the top-lock type wiper blades used on the Prius and many other vehicles to the most common U-hook type. I opened the package once for a test fit, but it is unused. Please research the compatible vehicles yourself. 10005025
