I went with a 12si 5 years ago and would never go back to the factory setup. The case can be easily reclocked to locate the output stud and air intake in a suitable location. Mine is spaced somewhat to match the crank trigger mounted under the crank pulley.I might have a pic from a year or so ago? I checked and have no useful pics of the setup. Andys right,it may not be as easy as it looks. In my case I wasn't using factory cylinder heads which may have made it even easier. They are cheap and if you can make it fit I doubt you'd find a better a setup.
