Rather than using needle nose visegrips to keep the trunions from turning, there will be a small hole in the very bottom of the tailgate directly below the trunion. You can insert a screwdriver into the hole. As you turn the bolt and trunion, there will be a slot in the trunion that will line up with your screwdriver. Once the screwdriver is in the slot it can't turn anymore and you can remove the bolt.
