Front bumper mounted turn signal bulb replacement instructions

Hi "oldturkey03." Thanks for your reply & assistance. I have a 1988 and the front parking/turn signal lamps are mounted "in" bumper. It appears that the only access to the back of the lamp mounts would be to remove entire bumper. Any ideas or suggestions other than bumper removal? For a photo of the front end lighting go to:
