Back to the original question: the bump stops are bolted on. Rusting apart is a common problem. Be careful getting the bolts out because if the Jeep is rusty they can shear off easily and you'll have to drill and retap the holes. Jeep gets too much money for these, but I've always gotten them at a local junkyard cheap. Usually the donors are sitting without axles, and you can just reach right in and get the stops, and who cares if you shear the bolts doing it? Try the boneyards first.
Or, if what you want is for someone here to sell you some, it might be better to phrase your question differently or put something in the classifieds. It's possible someone does have them if they replaced them for a lift.
