Replacing '98 Grille

The grille (plastic chrome part) lost in an exchange with a Toyota trailer hitch.

I've located replacements on the Internet. If I'm reasonably competent with a screwdriver, how difficult is it to replace this?

Thanks.

*should* not be hard at all.....now HARD is replacing my 87 Grand Marquis with a chrome grill from an 80's Cadillac thats 2-3 inches too high
