1970 duster buckets parts needed

I am in need of the cables and springs for the seat tracks on A body 70 duster seats. Anyone have any info on where to buy the new parts or have good used stuff around? I need the cable that goes between tracks, outer yellow springs, and the one big spring that returns the lever. Need the hardware for both seats. I see a couple complete tracks kits on ebay but don't need the whole deal. Classic industries sells the springs and cables but cables are on back order and springs are a small fortune. Any help would be appreciated. Thanks.
