can't help identify that, but here is how I mounted my visor
It came with 3 of 4 of these little clamps that bolted to the gutter, but the way they fit my truck the visor would either point up or down.
I made up a couple stainless pieces shaped to clamp on the gutter and hold it at the right angle
For me, the 'right angle' is to have the visor level with the door frame at about the same height as the top of door window
