I had a CJ hard top on my YJ. The biggest issue is if you run a spare tire on the tailgate instead of a swingaway bumper. The back hatch on a CJ has to open 1st so it's hard to reach behind the tire and turn the latch. Then you have to be careful about synchronizing opening the hatch and gate together. If you have a swing away, no big deal. I also ran CJ doors. No issue there at all.
