Im not a computer drawer by no means but here is a drawing of it.
It will be 50 mm stainless pipe with also the arch on top. And then it will be curving around the edge to the back of the fender.
The holder will come down on the back of the bottom of the frame and angle straight out far enough not to hit the hatch once opening or closing.
The arch should maybe be wider and higher?
I just traded some airplane aluminum sheets for the stainless pipe and his work. A neighbor of ours.
I can hardly wait to get it.
