Removing spark plugs in '03 Sport?

How? There is so much stuff in the way. How do I get to the rear most passenger side plug? Remove the A.C. stuff on the firewall? OMG!

From underneath and removing the rubber wheel liner.
Turn the wheel max left OR remove the passenger tire.
Anti seize the threads, they'll be in there for a while. GL
