Hello mate,
NO6 has two nuts, one on behind the bulk head and one in front, undo them both and you should be able to pull the bar to the left giving you access to NO8, you should already have access to NO9/10..... post if you don't and i will brave the cold to refresh my memory!
although i told you to take the whole lot out on second thoughts it looks a mare with the engine in.
Good luck
Rob,
