So I have learned a few things.  Setup is very important and certainly
contributed to the crack I had.  I suspect the plate on the mount
could be a little thicker, but that is for the engineers to figure
out.  When the nose gear is down and over center, the hydraulic
cylinder rod end should be aligned so the bolt slides in nose gear
weldment.  I set mine up so there was a little pressure to keep the
gear over center.  This stresses the weldment (which was fine on
mine), but also pulls the engine mount plate away from the firewall.
