Kiravans rail sail

[Ollie913]

Hi all , I’m looking to buy a rail sail . I’ve had one before for my caravelld but it was a left hand side one . I’ve now got a California which obviously has the side door on the drivers side . The one I’m looking to buy is for left side not right side . Does anyone know the difference? On Kiravan images it looks as though one side towards the front is longer

Any advice would be appreciated
