Dennis,
I got mine from Concours Parts in Carson City, Nevada.
They are the Ford side of Golden State Pickup Parts.
Part # A9AZ-7A650-A, $50

It's a universal trim-to-fit cable.

You can also get it from Dennis Carpenter.

They will be in town for the Pate swap meet.
You might be able to get them to bring you one and save shipping.

regards,
Leon
