You can see the gusset on the left of the shock(sorry
its all painted black) but its a wedge welded to the tube
down to just above the lower bar mount to kill the
side flex.... the lower hole where the lateral link
mount is sorta out in space and this stiffens it up..
boxing the rear of the bar mounts helps stiffen them
up... I dont have a pic of that completed.. but a
3/4" wide plate welded to the back of the ladder bar
mounts
EDIT
In this pic the back of the brackets wasnt boxed in
yet... I forgot till later
