I had a few hours waiting for the flight so I did a quick
and dirty estimate of the six G loads involved. It came
out to roughly 2800 pounds in the tube.

I rotated the tube in question to the vertical plane
and used graphical techniques to calculate the tension load
in the tube. Not quite as bad as I had first thought.
I would still put the diagonals in there.

I made some assumptions on dimensions which I did
not have. I estimated most of them from the pictures.
I assumed the front motors mounts where 18.5 inches
from the firewall. The joint where the three tubes
come together is 7.5 inches from the firewall.
The vertical distance between upper and lower hard
points on the firewall was 20.98 inches.
Your exact loads will vary depending on the exact
dimensions. This does not include the thrust and torque
loads which will add to the tension in one tube.

This mount has too many tubes, weighs too much and
is too expensive to make. Some of the tubes limit
your options as far as where the rads and exhaust
system can go.

Don't send responses as they may fill my mail box
and be lost forever. I'll be back about Thursday.
Hold your replies till then.
