Are you asking if its worth rebuilding? I'm always down to rebuild my own just for the joy of it but the costs add up quick and you may be able to find one to drop in I believe Quadratec has one.
If you decide on a rebuild and can afford it, I would recommend a stroker kit to improve HP and torque. It will not assist in the mpg area but will greatly assist the off road portion of jeeping.
