Spark plug replacement issue

[TheStablesMiami]

Sorry guys, i'm sure there may be a thread for this already, but i'm a newbie hahaha. I have a 2007 Tahoe LT with a 4.8. Im attempting to change my spark plugs and do a bit of a tune up, but i'm a bit stuck. I've managed to replace 7 of the 8 plugs without issue, but i cannot for the life of me get to the back plug on the pax side. Can some one give me a direction for a better plan of attack? I don't to just start taking things apart if i dont have to.

What I did is take off the front passenger wheels and go through the fender wall. Make sure you have some sockets extensions that angle....It's a pain and take your time. One tiny turn at a time...lol

That one plug took 70% of the amount of time to do all of my plugs.
