if we go with a 2" bulkhead for the emergency then the overflow box width will be 6" from the back of the tank , so if your tank is 30" the overall width is now 36" , as far as spacing goes from the wall as long as your tank is level then 1/2" -1" is more than enough, you need only enough space so that the box doesnt touch when the tank settles.
if we go with 1 1/2" drains then the box can be 5" and 4" for a 1" or 3/4" bulkhead.
we dont do smaller than 4" as it becomes impossible to work in.
hth
will have those diagrams shortly for you buddy
