Now I have swanky new front seats fitted, my little'un now wants new seats in the rear

So have been looking, and can see that the Range Rover Classic one's seem to fit straight in (but look a little dated if you know what I mean), but cannot seem to find a definite answer for the P38 ones, as they do seem a bit nicer with cup holders in the arm rest etc....

I don't mind a bit of work - have welder, will weld but would also like to know what I am getting myself into before I shell out a fair few pennies for the seats.

Has anyone had any experience's with different rear seats - as not a common topic really, as normally we are changing the front seats only

Please somebody let us know as I would like to do the same to mine
