ive fitted some to mine, to be honest it was quite a job as all i bought was the seat, i had to make mounts in the floor for the seats to lock in to and buy seat belts, i found rr front latch into the seat holster, but i didnt have the trim fittings so had to make it up as i went along, also the although the seatbelt anchor points are quite obvious they arent taped so need doing. mine work ok but would look better with the propper plastic fittings arround the holes ive cut in the plastic trims where the seat belt and mountings fit behind them.
good luck but if i had to do it again i would just sell and buy a 7 seater
