I used easybrackets, but I cut a notch in the back of each back to kinda mold them in. Also altered the easybrackets to add more attachment points to the bags. They are very heavy and going away soon because the harley bags are cracking all over and falling apart. My new Tsukayu bags are sitting in the living room and will hopefully get installed this weekend (with their brackets).
There are some pictures (though none of the backsides) in my bike gallery...
