MGB Flywheel & Ring gear

[Kendall Robinson <kendallr@smtplink.chey.com>]

          I just purchased a new ring gear for my MGB (the old one was
          pretty chewed up).  The only problem is, the teeth on the
          new one are stepped along one edge:
                          __________
                         |          |
                     ____|          |
                    |               |
                    |               |

               Profile of the gear teeth

          I'm not sure if the step should face the transmission or the
          motor.  Anyone done this before?  Anyone know?  I have a
          feeling the step should face the motor, where the starter
          first engages the ring gear.

          Any help would be greatly appreciated.
