Chuck: I would guess since there aren't a lot of people in your area, there aren't a lot independent commercial auto mechanics either. Those that are both familar with OD wiring and are reliable cuts that number down more. But look, KF cars (and other American orphan marks) are not complicated or particularly strange. You say you can't do the repair yourself, but I think if you can start and drive the car, you can either do it yourself or direct a younger person. You need either a KF Shop Manual (they are available) or a general manual such as a Chilton's Manual to show the electrical circuit and troubleshooting procedures. You would remove the original wiring (the original cloth wiring is almost always oil soaked and shredded) and duplicate it using new PVC insulted wiring and terminals.
You didn't say whether you had a new kick down switch. If you study the wiring diagram, you can see that a kick down switch is not essential to the normal operation of the OD; that is, you can connect the wires as if there wasn't a switch in the circuit. When I put an OD in my Henry J, the kick down switch had been removed from the donor car - everything else was there. I drove my HJ for several years like that until I found a switch. The OD will disengage if the speed drops below aprox. 28 mph if there is no load on the engine anyway.
By the way, you do know that you can MECHANICALLY engage the OD while moving - pull the OD handle out. But, you have to come to a stop before DISENGAGING the OD (and the freewheeling). Could be scary going down mountain.
