I did the egr on my 09 JK two weeks ago. That's the pic I have on my profile. With all the emotional outbursts and trips to the store it was about a 5 hour job to complete. I ground down the face of a curved wrench to get more clearance and ground the shaft to about 3 inches. Mine is an auto too so we pushed the trans pipe back from the top with an I level. The hidden bolt was the most difficult as once it was a bit loose, I did the rest of the turning by hand.
When it was all done I took the old part and hung it on my garage wall. Lol, the girlfriend laughed at that one.
