Haha I plan to do exactly that. After all; the rear seats need to come out at some point to accommodate the Viper V10... :lol: Nevertheless I'm back to uni tomorrow; hence it'll have to wait.
Bad news! I attempted to remove the back seats from the Kangoo and the middle support does have a clip; and its a much more bitchy clip than the outer two. Some sort of spring clip with a notch to get over - it will require much hammering but I shall succeed (it just won't be today ).
