Cracked the rear bumper
 

Hey guys. The other night I backed into a gas station concrete post, cracking the back bumper of my 04 Montero Sport. I was wondering if it would be difficult to change out the bumper myself. It seems to me I just have to remove the bolts underneath the liftgate door, and a few moor underneath the car. Is there anything else I should keep an eye out for, and is it even worth doing on my own?
