Here are a couple shots of what I have now. I see that I need to tighten that cable nut before any more driving.

Notice the black bracket that the cable housing mounts to. That is just a 1/8" steel plate bent 90 degrees with some carefully placed holes. It bolts to some cast in bosses on the #8 intake runner. I don't remember if the manifold Gene has now has those bosses. One could just make a bracket that used the two rear carb studs instead.
