Modern cars with a more swept back windshield tend to have longer wipers. 19" plus isn't uncommon even on a 2 door car.
In regards to the frameless wipers, I've used them, you do have to take the natural bend out but they worked fine. On the pair I recycled, there was also a slightly thicker piece of metal as well that the whole wiper was built on. I plan to make some thicker tension wrenches out of that piece.
