Has anyone done the Rocker Replacement on an MJ?

I am thinking of cutting off my rock rails and doing the rocker replacement thing that many are doing on their XJs. Thing is I have an MJ, and have never seen it done... has anyone?

things are a little different on an MJ, so it may make things a little tricky. my main concern is what to do behind the cab? I have the bedsides cut up to the body crease, so I guess I don't really need any protection behind the cab...

ideas?
pictures?

thanx
