I had to do some cutting, grinding, and welding to make my seats go onto the OEM bases. And it was a total PITA, but it was also totally worth it. I installed a couple of seats out of a wrecked Volvo and after installing the seats I wired up the seat heaters, awesome! So I would suggest you contact the seat maker and see if they make a base that adapts the seats to your Jeep. If not you may have to get creative.
