Wj what do I need to know before I swap a rear JK D44?

do i need extended or different brake lines?

what about emergency brake, what do i have to do for this?

i have the rear drive shaft from the 4.0L V8, that was mated to a 242HD, will this be a direct bolt on to the JK D44?

since i have the non-Rubicon axle, i don't have the e-locker, so no need to worry about any wiring for that.

not really worried about the spring, shock and sway bar mounts, as those will all be custom done.

anything else I didn't cover and should know about before i get started?

I think you're good for the most part. Your single brake line should mount to the JK brake line at the T on the axle. You stock e-brake cables will attach to the new JK system.
Don't know about driveshaft as that would be custom to your setup.
