Just wanted your advise on this before I progressed too far with it.
Decided I didn't want to spend another $100 on a 1/4" x 2' x 2'
piece of aluminum to go between the engine and oil pan.  Besides,
I have a fully assembled 13B on the garage floor and didn't want
to remove the pan again.

So I'm trying to use the stock mounting points.  This would not
be supporting the engine/psru (/duct in my case) near the cg, but
slightly in front of the cg, at the center side housing.  Also,
the drawing was assuming the use of a 12A front cover to mount to,
but could one drill holes in those two flat protrutions on the
front of the 13B to mount the front struts to?

I'm mocking this thing up now on the engine with cardboard tubes
and 3/4 inch dowels.

One advantage you have is you don't have the weight of the PSRU.
What does that prop duct weigh?

That looks like that will work fine Perry. Make sure the bracket
bolting underneath the engine in the stock mount position  is stout.  
Make a detail drawing of that and up load it. Probably something
like 3/4 aluminum plate would be called for here.

Pick up some pan bolts up at the front  along with the 
holes in the front cover just to be sure.
