Hello i have a 5 door saxo and have an issue with the driver seat, its rocking back and forth, the rails are knackered it seems, the floor is also cracked and i will.reweld it when i get some chance, the question is how do i solve the seat issue? Is there any way to repair the existing rails? I cannot find any used or new rails or even a goof used seat for it
