any help on this one and i'd be most grateful

my local ford dealership currently have my car after the clutch cable snapped over a week ago

and they cannot find a cable the same as the one they have taken off the car.When i bought the car I was told that it had had a mk 5 pedal conversion carried out which i have no reason to doubt.
Following a previous post last week i was told by a few people that the standard cable is still used with this conversion but ford just dont seem to be able to locate the correct cable.
Does anyone know of anywhere that i could maybe send the cable to and have it matched up to get the correct cable,
