Honestly, it's really not that hard to just unbolt the links at the axle. If I recall, all you need is a 5/8" box wrench and a if you have one, a 3/4" gearwrench will get you disconnected in minutes. It's what I did after my Rubicon e-locker took a dump and before EVO came out with their No-Limits knob.
Otherwise, I would keep an eye out for a used Rubicon e-locker even if it isn't working. The Antirocks will LIMIT your flex and I personally would NOT recommend one.
