Forgot to take a top view shot aft= er assembly, but here's one of just the plate after welding, with a test fi= t of the shackle bushing. In a weeks-long fit of paranoia, the decision was= made to pick up every available tie point. The bolts that are in shear are= interference fit to the threaded holes in the motor.

Many thanks to Monty Roberts & my neighbor, Andy McCain (both = are engineers), for many hours of unpaid consultant work, and to Andy for welding skills.

It's try-angry-lated. The two white inner, more or l= ess vertical tubes attach directly under/behind behind the capture points o= n the horizontal square bar. The new top-down diagonal catches the top; the= new bottom-up tubes catch the ends. Off-axis load paths are at least as go= od as most dynafocal offsets on proven mounts. The load into the bar should= be more or less at a 45* angle toward the bottom of the firewall, minimizi= ng the twisting load on the square bar.

I considered adding another diagonal between the two original vertical tubes, but it already h= as as much angular bracing as the original dynafocal structure.
