I got the right parts today, Rain-x Quantums. They only came with one clip, no need to remove any other part, there is also a spare cover plate/clip but it does not fit with our wipers that I can tell, but they fit okay with the standard clip.
So far they work well (as a new wiper should), we will see how it does in cold temps, we are just above freezing today. I don't care for the rain-x product that is applied to the windshield, I usually find that it ends up streaking in the long term but we will see how it goes. So far so good. Thanks to all who posted up info and part numbers, much appreciated.
