How do you change front bumper on 87 Nissan pickup?

To change the front bumper on an '87 Nissan pickup, first, ensure the vehicle is on a flat surface and secure it with wheel chocks. Remove the screws or bolts securing the bumper to the frame, typically located at the ends and sometimes in the center. Disconnect any wiring for fog lights if equipped, then carefully pull the old bumper off. Position the new bumper in place, secure it with the bolts, and reconnect any wiring before tightening everything down.
