Why would you need new soft lines? I'm getting ready to do this job as part of my axle service as well, and don't remember reading anything about the brake hoses needing to be changed, can you clarify?
The ends are slightly different if I remember. The banjo fitting has a little spur with a pin thru it that locates the fitting on the caliper. I seem to remember the distance and placement of these pins being different from the new to old caliper, but I have slept since then. I think I have my old calipers in the garage and I can see if I can get a picture for reference tomorrow.
