If the flywheel is position sensitive, there two methods used commonly:
1. one bolt (or more) is offset from the others, thus preventing installation in more than one position.
2. one or more dowel pins will be used, with an offset pattern, to locate the flywheel.
If you do not see those, assume it is not position sensitive.
