I tried needle nose pliers (didn't fit), a regular box wrench (didn't fit). socket (ha), and then decided to try one of my craftsman flare end wrenches... it fit like a glove.
There is a special socket for this replacement. I've also seen some "normal" sockets with a groove cut down the center. Not much torque is required... hand tighten and then another 1/4 twist.
Since I began working on my 911 I've become very crafty in my approaches to reaching things.
