standard seat rails

[dnb]

Does anyone know where to get some new seat rails or what car they originally came from? Two of mine are doing a good impression of lace.

Thanks.

I've no idea where the runners originated from though others may offer more help. However my runners look like this and may be worth a try if they can't be found anywhere else.
