Do NOT brace the housing to the skid plate/pan, that will transmitt any shocks directly to the housing when it impacts an immovable object.
A simple strap over the snout is all that is required to keep the aluminum housings and thirds happy and unbroken. With the stock mounting point, the snout is allowed to torque in a rotational plane and place sideways and rotational pressure to the snout .
I have a buddy that was forever shattering the thirds running a locker and 32's, he went with a steel third and started breaking housings. He went back to aluminum thirds but added the strap upgrade and has yet to break another third or housing.
Another option as you have aluminum welding capabilities is to add another mounting block onto the snout on the pass side of the snout and a additional mounting location on the cross member.
