I am looking into the stock brackets now but another good option would be for you to look at a full traction ultimate lift kit. That would give you a tringulated rear upper and you would only need the spring buckets and shock mounts then. The front is not an issue anyway as the three remaing brackets are oem now anyway.
Also if you already have axles with stock brackets on them it would be pretty darn easy to cut them off and move them to these axles.
Also I was assuming you had a TJ but then I saw your signature and though it might be an XJ which would make it even easier to do.
