access to front lower control arm bolt

[LightlyToasted]

'07 4.8i, no adaptive drive. I need to change the front lower control arms, but am having difficulty getting access to the bolt and nut on the front of the arm (not the ball joint) especially on the left side of the vehicle.

I've removed the central splash shield, and the 2 smaller plastic shields.

I can get a wrench on the rear-facing nut, but can't seem to get a socket on the head of the front-facing bolt. It looks like I could get access if the brake air duct were removed. Can the brake air duct be removed to get access? Or do I have to remove the whole wheel well liner?
