Depending on what you are looking for, how new it neds to be, etc... another couple options for used OEM stuff might be:
Rubicon Recyclers; Flea-bay auction site out west, has lots of take off parts from wrecked or other totaled Wranglers. Mostly all TJ stuff, although certainly not all Rubicon gear.
Another "recycler" of used OEM parts is Rancho Cordova Specialty Recyclers. They are actually a network of auto dis-mantlers out west, so most of the stuff is rust free. They tend to have more models available, but are kinda hit or miss, especially if it's an odd part. They have a yard for just about any make/model you can think of, so anything you need, they might have!
