I run front and rear sway bars on my 57, I believe a 1 inch in the rear. My front is 1 1/4 inch, it handles great so I understand how you would want a rear one.
I had the issue where the up and over part of the sway bar didn't have space do to lowering the truck, the bed floor was too close to the differential. I looked at every conventional way to mount it. As I usually do, I stopped thinking within the box and relied on theory and how a sway bar mounting makes the sway bar work.
My pics will explain from this point. Your exhaust pipes will probably get in the way of most sway bars but I can't tell by the pics.
Anyway, I thought I'd throw something different out there.
