273 4 bbl throttle cable clamp

That looks different than the 4 bbl one I saw on an automatic (which looks like the two bbl only backwards and taller).
How does this work since I do not have one to go by? This is for 1965 273 4 bbl manual?

The unpainted one is for a 67 273 4bbl and MAY fit other years, Im not sure...maybe Keith 66340sedan can shed light on it??
