     Largest diameter is about 15 inches for the bolt flange.

     Here is what I have come up with so far. The flat lower sides
     can be used to bolt on your fabricated rubber bushing brackets
     of choice. This give a maximum amount of flexibility as it
     seems nobody can agree on just how wide they want their rubber
     bushings to be. It is rather more complicate inside as various
     and assorted ribs are required to provide support for Tracy's
     PSRU.

     What does everybody think?

     One consideration may be that it needs openings for air flow.  The elastomer vibration
     dampers are in there, and in doing their job there is heat generated.  I have no idea
     how much, but it needs to go somewhere.

     Perhaps there could be an option for those of us who would like the starter on the other
     side.  Or maybe I'm the only one :).

Putting the 86-93 starter on the other side is just not practical as
the bell housing bolts get in the way. Not impossible just extremely
difficult with a pattern sans core boxes.
