bumper damage

I got into a minor fender bender, and would rather do the work myself instead of giving MORE money to my insurance company. I found a nice looking coupe bumper from a 7gen. Will it fit properly on my EX sedan...((I KNOW IT SAY COUPE)), but I was just wondering.

I found a huge crack on the passenger side of my front bumper, no scratching so I don't think the car hit anything, I would've definitely noticed anyways. Unfortunately I don't inspect the car there often and only noticed the crack yesterday evening, so I'm unsure how long it's been there...
