That's a good write-up I used it too.
I'm liking my footman loop no drill mount. I did a quick write-up on it here-> http://www.jk-forum.com/jk-cb-ham-ra...8/#post3011242
I would recommend taking your antenna wire up the rollbar. It will work out way better then the floor.
Another tip is to put some hairspray in the antenna cap after you adjust the SWR. That should keep it nice and tight. It's how you install mountain bike grips.
I was thinking that the mic wire would annoy me with it mounted up there. I put it on top of the radio when I'm not using it and you can clip the mic in and it will stay out of the way.
