The raptor front buckets are very comfortable. I would suggest buying seats from someone on the forum. I've seen seats that were taken out of serious offroad builds. Foust Motorsports in Mesa AZ builds a lot of trucks, try them.
The rear seat with both halves would be too wide for a jeep. The wider bottom might fit, but the rear seat back is one piece. It would likely be easier to hire an upholstery shop to fabricate a seat cover that looks like the raptor for the stock rear seat.
