If you moved it far enough back that you could run it to the back side of a double arm like a 4x4 labs arm, but I don't know if I've seen that done.
Is there a reason why that couldn't be done?
I know you couldn't use both sides of a 4x4 labs set up. you'd have to run just the right side...
You would have to get a box that rotates backwards. Pretty much means an Astro box if you want to put in a saganaw and want to keep it inside the frame rail.
It will not work with your current box.
