M104 EGR tube bracket bolt on back of head

[nazrat]

I'm albow deep into my wife's 1995 C280 trying to replace the EGR tube. I have it unbolted from the intake manifold, and totally removed the EGR valve itself. I've removed the bolt that holds the tube next to the oil filter housing, but I can't seem to get at the bolt at the back of the head. What's the trick here? I can't actually seem to find a way to see the bolt.

Someone must know the trick.
