Is the place that you found it for 117$ Bernardi Honda parts? If so, I'd call them tomorrow during the day and just ask. I'm sure if you give them your VIN they could tell you which assembly is the right one. As for how easy it is to replace... well it's probably not very easy just based on how the stuff on the front end is assembled but maybe you'll get lucky. Maybe you'll save 200$ and learn a lot about your truck and also waste 6 hours of your life. That's probably worth it still though.
