I created a post about this about 2 weeks ago. Should be helpful. I too, ordered and received the handbrake cable kit from Ford but only received the twin cables after the Y-Junction with brand new return springs.

I am calling Steve at Tousley Ford again today to find out why I did not receive the end that goes into the hand-brake lever which is the one I need. Still replacing the rest anyway though, since I am upgrading my entire brake system and it cannot hurt...
