I second looking for a local wheeling club. I had this happen to my daughter's ZJ last year, except the one side of her t-case skid fell out of the unibody frame while she was driving it. I limped it home and had a friend come over. It's really not that bad of a job. We cut out a 4 foot section along the bottom and then welded 3/16 c-channel back in place, brought it all back up with a floor jack, drilled new holes and then dropped it back down to weld nuts into the backside.
