I Have a Mclouis Lagan 410 om a Fiat Ducato base. I need to remove the driver and passesnger seat so i can install new leisure batteries. Has anyone removed these seats before. I note there are 4 special allen type bolts with a star shapped recess in them and i suspect that's a special tool which i will have to go to Fiat for ! Anyway, would i be right in thinking that if i remove these bolts i can just lift the seat off to get acess to he battery bay underneath. Thanks in advance. Philip.
