I dont have a crawler box. And that transfer case is a forward shift.
But I suppose you could take the rear storage compartment off the back, take off the lid, section the inside into 2 sections and put the shifter inside.
But when I put a crawler box in (at the rate i am going, I probabally never will, expecally since i am thinking about selling the truck because I dont use it enough), I will probabally make a center console.
