The crack wouldn't be visible, the passenger seat would be in front of it. It's fairly easy to install, a bit unwieldy because of the size. It just pops in with a bunch of clips. Do you have an existing waterfall? The reason I ask is one of the clips is missing, so you can just swipe one from your old one. Price isn't firm, but not soft either. What's your zip code so I can get you an estimate on shipping? It'll be fairly high due to the size.
