Here are pictures of a barracuda we are doing right now. We installed a frame on the assembly to make the z-bar to fit the headers. You can see the difference of the fork location compared to yours. Some of the aftrmarket bells you need to use a different fork depending on the pivot location in the bell. There are also different pivots which move the location of the fork.. I am lucky to have all the different styles here to mock up what is needed.
It is much easier to fit parts using a fixture . easier to make mods without the car body in the way. Hope some of these pictures help
