Answer:
Don't forget to disconnect the side marker lights.
Remove 2 bolts on both sides behind rear wheel wells.
Remove the 4 bumper support bolts located inside trunk (this is what I forgot).
Remove 1 bolt on each side of inside of rear quarter panel on inside of trunk.
Maybe be more bolts connecting bumper cover behind rear wheel wells, not my case as they were either gone or rusted off.
This gets the whole thing off.
Once it is off you can remove all the bolts holding the bumper cover on. Or in my case... torch them off as they are not 10mm heads anymore.
