Yes. It can be fitted onto a CJ7 chasis but there will be a few mods that will have to be done.. Apart from the others:
- If there is and discrepancy in wheelbase of the two vehicles, the CJ chasis will have to be elongated that much
- The wrangler diffs are wider than the CJ and the body is wider accordingly. Maybe if you take off the flares, the width will be fine or put in spacers (undesirable) or wider tires. Otherwise, the CJ diffs may leave the tires short of the flares.
- The mount points will have to be modified to keep the body at a parallel level to the ground. Get a good experienced Frame welder to get this done.
Just what I can think of.. I may be wrong..
