Be sure to get the same style muffler clamp...you need to tighten it around the bumper strut from the top and bottom....the "U" shaped clamps won't work. I used stainless steel bolts when I did mine...they looked a bit better and won't rust. I also rustproofed the strut with POR 15.

And I don't let kid drive the car...
