I still have all the stuff I took off the truck when I did the conversion. In addition to the manifold/carb change, I replaced the ESC system with the standard Chrysler electronic ignition distributor and module (from the same donor car from which I got the manifold stack). The ESC air cleaner, while being taller, fits the Holley 1945 carb, which has a different air horn diameter. It isn't usable with the BBD. There may be a tall ESC air cleaner that fits the BBD, but the one I have isn't it.
