Parking brakes with 8.8 inch ford rear and disk brakes.

If the arms on the calipers are pointed such that they are clear of the suspension, etc, "it should be easy." There are various rigging outfits that can make up cables with crimped eye or knob ends, etc. And that in combo with some of your existing hardware you should be able to devise "a hookup." Just hink carefully about how it all moves, and don't end up with a bad leverage situation where, even though you can pull on the brakes, they don't create actual braking force. You don't need "encased" cables, they can all be bare up to the connection to the upper cable assy
