Yep, I took pics but i can't find them. You can see where the top three screws are. Each of those represent an L bracket with a screw securing it to the inner lip of the fender. I used aluminum bar just like you did and it is secured to the fender lip via 2 screws and to the bumper lip via 2 screws.
I am basically planning on building a green version of the blackfly
. I want to do a camback that will be almost identical to yours accept the plastics place near the marina has clear corplast so I'll probably do a portion of it in clear. Also a belly pan is something I'd like to do soon but I hope to do a kill switch and miror delete prior to both those.
fun fun fun
