This adapter is for attaching U-type wipers to the wiper arms (top lock type) of Daihatsu and Toyota vehicles. I tried it on a car, but didn't use it and have been storing it. ◆ Quantity: 2 ◆ It seems that the wipers will collide if the wiper blades are the same length as the original ones, so please check the PIAA website, etc. ◆ Wiper blade holder ◆ Special arm compatible holder ◆ Can be replaced with PIAA rain wipers and snow wipers Compatible vehicles: (as of November 2015) Toyota: Alphard (H27.1～), Vellfire (H27.1～), Sienta (H27.7～) Subaru: Stella (H26.12～) Daihatsu: Move (H26.12～) ※ Please check the manufacturer's website for the latest information.
