Have a 2002 base model and the left rear bumper cover has come loose. Pulling out the cover from the wheel well and looking in tells me little as the brackets/mounts have rusted away (however the exterior still looks pretty good). Bumper cover removal instructions say go in through the trunk and remove bolts on the sides...my problem is there is nothing between the bolts and the left side of the bumper cover. What parts do I need to reattach the LR portion of the bumper cover to the vehicle? Many thanks for your input.
