I just got some new wiper blades from the parts store, there the universal type that can take the hook and loop attaching method or the bayonet attaching method... my old Ralbler is the Bayonette type attaching method and the old blades are only for that, not universal like the new 1's.. the new 1's have a thing that acording to the directions, flips in or out to whichever method the car uses, but the diagrams are so vauge I can't understand where it goes in these new arms.. any ideas?
