The bumper bolts are in the trunk and the splash pan bolts are in the trunk/fender wells. The bumper comes off with the mounts, then you unbolt the bumper from the mounts.So how does one get it off exactly. It appears my lower valnce under the bumper has been permantly attached to the 1/4 panels. And I can't seem to see the back of the bumper bolts. How do you remove the rear bumper?
