For it to be able to be so misaligned seems impossible - for the main casting to not be designed D shaped, or have a flat edge would be deeply worrying.
I think that it's been established elsewhere on the thread/s that there are lugs or something that means that they can only be installed in the correct orientation - but tdracer has said that he has seen them carefully machined off so that they can in fact be incorrectly fitted...
