These custom made brackets can be used to install only the two inner driving lights on, the outher two must be installed on the metal bumper itself where normally the low impact absorber is mounted on. The brackets will only fit the ’82 model metal bumper. In case you have a newer model, we are not sure or they will fit, maybe they do, but you probably need to drill new holes in the metal bumper then. One set is needed per car, you can not install more.
