For your files.  A prop extension.  The inner boss doesn't look
like it extends one inch upwards though.   Source is AirCraft Spruce catalog.
Say recently  Google has linked images to a website.  Much faster

Check out this companies compact SR  water cooled alternator/ and
starter motor.  Nice and compact.   SR is is a very efficient way

Good-bye starter ring and starter?
