A friend of mine has a Hunter Legend 43. While not the exact same setup, it has the two wires crossing before going to the quadrant (like your problem).
And it failed at one point (of course in-oppurtune time)
Since their steering wires run across a flat recess, they put a harken block #108 on the flat recess at the point where the two steering wires crossed to deflect one of the wires up about 1/2", just enough to prevent chafe, but not so much as to screw up the steering wire leading to the quadrant or from the wheel.
