Where to buy acc. cable for 66 Dart?

I have a 66 Valiant 340 4-speed, I used a throttle cable from a 1973 Duster I parted out. It was a 318 2 barrel car and it fits great, even with an Mopar Performance M-1 intake and 1 inch carb spacer! I would think any a-body V-8 car 64-76 would work. :thumleft:
