When I installed my Crown extended brake lines the hard lines in the rear seemed to fit just fine by attaching the new lines to the drop bracket that comes with the 2.5" Lift kit. I attached this way and thought it was the best location given the bracket pulled the line further inboard and away from the rear sway bar. I did relo the front but the back looked just fine. Well, I'm going wheeling on Wednesday and decided to check the rear flex, here are some pics.



RH side- Too close for comfort




I decided to redo the install the rear. Drill a hole, put in a screw and put the mounting point higher on the Jeep. I simulated flex and even though this is further outboard it is higher and is out of the way better of the rear trackbar.



Here is a pic showing the new mount, next to the stock location. TF 2.5" brake line extension bracket removed. I used the write up here to complete the install. Maybe you can use the stock location, but this is what I did. Hope this helps you out.
