d4 rear seat bench

[nath]

anybody care to enlighten me how the hell you remove the rear seat bench
i am aware of the 3 clips at the front edge of the seat
and removed those easilly
i am now trying to release the rear part of the seat which has either been glued or welded in it would seem
there is some type of clip holding the outside of the seats
but it doesnt appear to want to move either up or down
the only other thing i can see is a bolt which holds the bracket to the body
but this is obscured by part of the seat frame

need to remove rear seat to enable me to thread wiring for rear camera
thanks nath
