The vents were moved from the hardtop to the tailgate... I believe that started in 2003? So yes, it's possible that if you have a '02 or earlier TJ (no tailgate vent) and get a '03+ hardtop (no vents), you may have a mild issue with the Jeep being over sealed. Either install some junkyard vents in a newer hardtop or swap out your tailgate with a vented one. That would fix the issue for sure.
The only fitment issue would be with the Unlimited TJ hardtop. Obviously too long for a regular TJ.
If your Jeep came from the factory with just a soft top, you would have to install proper wiring for the hardtop's wiper and defroster. Unless you don't care about those working. You also need to make sure you have a tailgate seal, which goes on top of the tailgate.
