Hi Hazel, it's unusual for the springs to get that bad but I guess it can happen they usually go weak and flatten out. A member on here had a set of springs made at Jones Springs in Wednesbury (sorry I don't have the contact details) but there maybe a company local to you who would do the same, Jones will have the pattern for them so it might be worth a trip. I would also get a second opinion as it might just be surface rust and road dirt making the springs and hangers look bad. Try Speedy Spares of Brighton for the spring eye bushes - you will need eight in total but they are cheap.
