My truck did not come with a top. Does anyone have extra hoops/frames?

Pretty expensive to buy. Thinking I could make some.

Can someone send me a profile photo of the window frame, where the window meets the roof hoop frame...3 in the schematic below is the whole part, I really just need to see the part the window comes in contact with.

I suspect it is just angle, with a rubber seal, but I have never seen one in person, so a photo would really help me out.
