Yes and no. The floor brackets are definitely different between XJs and MJs since the floor is very different (you can use the floor brackets from an MJ bucket seat under an XJ seat). The 4-door XJ seat doesn't tilt forward like an MJ's, only the 2-door XJ seat does. Also, the XJ seats with the curved rocker slider will prop the seat up a couple inches higher than a stock MJ bucket. Power XJ seats are about worthless since you can't use anything but the seat itself. So the only stock-replacement candidate is a 2-door XJ seat with the straight slider and you would still need MJ floor brackets. But any XJ seat can be made to work with fabrication.
