The main two differences is the CJ5 has a 83" Wheelbase and the CJ7 has a 93" Wheelbase. The door openings are different. The CJ5 has a S shaped opening and the CJ7 has a U shaped opening. The bottom line is the CJ5 is just smaller. Other than those 2 things they are basically the same vehicle. Of course there are other differences in appearance and trim.
