Depends on how much work you want to do. These I believe use the existing holes from L bumper.

Otherwise there are the original bumperettes which come in 2 styles, rounded or squared ends. They require body work to fill the holes left behind when the L bumper is removed however. There is a company that manufactures them in stainless but I've heard there may be fitment issues.
