I doubt you will find a "used" one. Its one part on a Jeep that usually does not ever get removed. If someone upgrades a t-case, you might find the whole case, but most people wont take one apart for the SYE, it makes the case worthless....
Absolute Offroad has pretty good deals on them NEW, you might check it out @ www.absoluteoffroadphx.com
