You removed the plastic trim underneath the headlight? pull forward on it from grill side to pop it out, and them pull sideways towards center of truck to remove it.
You got the bolt from the bottom? accessible from under the truck, I removed the fender well splash guard to get to it. Its on the backside/bottom of the headlight. Once you free the headlight, the real fun is getting it angled and rotated to be removed. I taped everything up as not to scratch it all up.
