Are you replacing the axle with the same type ? Me and my buddy TJ cheated when my 10 bolt came out and 12 bolt went in. We didn't crack open a single brakeline. We unbolted the backing plates, gently removed the brakes and lines from the axle , slid axle out and slid new axle in, bolted up my 10 bolt backing plates ( with brakes attached , hardline and all ) directly to the 12 bolt, even the hold downs on the tubes for hardline matched . Was cheating , but hey, it worked /forums/images/graemlins/thumb.gif
