My MC-8 has a mechanical tach drive next to the water pump but is missing the internal drive in the engine. I have a Hall-Effect generator that will operate my Stewart Warner tach and I have it all installed on to find the missing drive when I went to install the tach generator. I'm wondering does anybody out there have the needed parts or know where to locate them. Also if anyone needs a gear drive, 24V, oil cooled alternator I have one that needs a new home. Thanks.
