I saw what the problem was, the bracket which is fitted to the inside wall, was about 10 cm shorter than the one on the right. this also meant that the locking bar which is in the floor is no where near the catch on the bottom of the seat.
Can anyone tell me, if there is a difference between left hand drive and right hand drive, when it involves these seats ? The Discovery I own is left hand drive, and the seats were bought in the UK.
I hope one of you guys or gals can help me with some answers.
