What Bob said is correct, it is not difficult to create a tower to mount the bellcrank on, but it must be placed properly or you will never get your cabs to open equally. First of all assuming the fuel lines attach to the outside of your carbs(?). The following will then apply and can also be used on manifolds that already have the mounting tower cast as part of the manifold. Remove the carb mounting nuts (if you are using studs) for the 4 studs on the inside of the center 4 carb throats. Stretch 2 rubber band attached around the studs to form an "X" in the center of the manifold.The small diamond formed by the intersecting rubber bands is wher the hole is to be drilled to anchor the bellcrank tower. If you already have a tower cast in the manifold you will probably see the attaching pivot hole needs to be moved about 3/4". Design what you will carefully, your carb syncronization depends on it.
