make sure you have not only the bumpers, but the two sets of black rubber sides, and the metal brackets that are hidden under these rubber pieces that hold them onto the body and cover the ends of the bumpers. if you have all the right parts, they are plug and play and the installation becomes obvious once you pull the old ones off and get under the car to look. they're aren't that many options to make a mess out of the process. and yes, you'll be left with two holes by the rear bumper rubber that you have to do something about.
