Originally, I had the bags hung over the stud for mounting until I "hard mounted them" to the frame further back. But now...Yea, that's the idea and what I'll call it...LOL. I doesn't need it, but when I rotated the fender back for valve cover clearance, I figured I could fill the empty hole and call it that now. I like the look of the fender rotated back better also, so it worked out that way...
