Need a new Shifter Cable for 1991 Ford Festiva GL automatic. work just done at Lee Myles. Part obsolete

New part preferred. Live in Queens, NYC, but I'd order over the world wideweb if no choice. Ford said new part is obsolete. Lee Myles can't complete their own rebuilding job, and linkage is really faulty without a good shifter cable and hardware to hold linkage steady. Oft times, car does not get into reverse or drive because of this.
