Hi All. Does anyone know where to get new rear leaf springs for a 1972 MK1 Capri Pre-facelift.

Do any other springs fit. I guess they would have been common to many 1970's models?
Maybe MK1/2 Escort, Cortina or even MK2/3 Capri's?

Or is it possible to get them re-tempered?

Thanks for any responses.
