This morning as I was backing out of the driveway I inadvertantly clipped a low-level brick retaining wall. Seemingly not that serious but when I got out of car (2000 model) to check it out I found that with a slight tug the entire front bumper section came off. Closer inspection showed that a couple of the black plastic screws holding the black underpanel in place had broken off but I was surprised to find no evidence of screws ever in place under the hood to hold the entire unit in place. My immediate fix was to transplant two bolts from my lawnmower handle into the two holes to the right and left of the radiator. It's holding so far but I'm wondering if anyone else has had a similar experience. The underpanel has been torn from the screws in a couple places above the wheel well and will likely need to be replaced. Can these be purchased separately?
