You can do away with all the ribs.
Your foundry will love it.
Your machinist will love it.
Your welder will love it.
And Tracy will love it.
The 1/2 inch square .035 4130 steel struts are bolted to
the bell housing with two 10-32 screws each.

To tell the truth Paul, I was wondering how to do this for some aerobatic
applications - that's sure solved one problem - that's the ultimate in
strength and rigidity for the PSRU and should be light as well..
However I'm not sure how that affects the MM  area, the ribs did provide
some stiffness/ strength to these areas.

Now as the face can and will be imperfect because their can be some
distortion in the foundry process but four pads at the perimeter will solve
that - they can be milled flat with the PSRU face pad - another problem
solved.
This could also be varied to accommodate different length prop shafts for
different applications.

Is it starting to look too Agricultural !?

That's OK :)
