Thanks guys. It's the flush, or slight overlap that I am having issues with. If I can adjust the belt down about an inch, I can eliminate that gap between the back and kidney, while still leaving the kidney aligned with the ab plate. Being able to raise the ab plate, allows me to raise the chest, keeping the overlap and pushing the shoulder straps down and into proper placement on the back.
I'll get with the GML to make sure it's ok to move the belt down.
