Here's one of those:-----The Bellhousing's 8:30 mounting bolt.

The attached shows a very easy and light way of dealing with this by
means of
a Webbed Boss...Since my original comment of the mounting hole not being
needed still holds, this position can be used as an alternate place to
mount
the Starter by simply cutting the web of the Boss and removing it all-
together...Since a hole is needed for bolt access, I suggest Tracy's
Starter
hole be machined in both locations as the base point for other Starters
to be
fitted in (Die Ground) as Paul has suggested, the bonus is: the unused
one
will act as a lightening hole :)
George before you jump in, I'll beat you to the punch and state, that an
extended Boss and or Webs to the bottom of the channel is overkill and
only
serves to add weight, expense and hinders Starter mounting hardware
placement ;)

Butch,
Not at all mate-I agree on your entirely as this was one of the solutions I
came up with as well, simple and light.

However my concern with this approach was the attachment to the housing, if
it were a separate piece.

As it is it can't be cast in, UNLESS it's made integral to the housing (the
same as I made the internal reinforcement ribs in the prototype) and THEN
cut out with the starter snout hole. This then would leave more material
than your drawing depicts.

If it is a separate piece and not firmly attached to the housing - I can't
see how that would work?

As you can see I'm giving everything plenty of thought.
