Outer Limits 4x4 Board

I need to replace the seats in my F60. The rails are buggered and I would like something a bit more comfortable.
Does anyone know what seats will fit the F20/F50/F60 series with little or no modification?

I have a set of seats avail for a feroza . Will these fit?

If the total width is under 500mm
Does it come with seat rails and what are the rail spacing?

Thanks
Sweeney
