I finally got a chance to compare brackets and calipers and they are all the same size. I flipped around calipers from side to side and still end up with the same result. Frustrating.
I was also able to find a 16"x6" 8 lug wheel with 4" of BS and mount it up to the driver side. Wheel fits, caliper does not rub whatsoever, however, there is only 1/16" of space between rim and caliper. Too close for comfort? Should I just go to a 17" wheel making the side to side differences a moot point?
