My passenger side blade ripped in this last snow storm and I was going to replace them. I got these Peak wiper replacements, but I can't for the life of me figure out how to get them installed. Looks like I need to somehow detach the 3-piece plastic shroud on the original blades and put them on the replacements. Either that or somehow remove the blade part from the replacements, not using the arm and somehow put them into the original arm on the car. Here is what I have. Replacement wiper is on top.
