Hey Rob,
I had a couple pics posted on my PB write up thread but here is how I have mine mounted up in front:
The rear is similar to those already posted, mounting at some point, inside or outside the trailing arm.
I believe one of the ways that Nate and PB recommend or have set up most of their installs is like pic #2, with a adapter plate mounted on the inside of the frame rail for the e-level sensor and the rod attaching to a fixed point on the trailing arm. A collar shaft is probably the best option if you have tubular arms.
