Had to change the long front wiper blade on my car, bought a Bosch replacement from G+S but it didn't really match the factory blade. I had a look at the design and found the rubber blade section is the same as on old cars, so I dismantled the old factory blade and the new Bosch one and reassembled the Seat one with the new Bosch rubber blade slid into it. Used a small flat blade screwdriver to remove the endcaps, the aero elements just pull off and stretch back on. Result is new blade with factory design at 1/2 price.
