Front window shield: how to hang it?

[Uncle Cereal]

I'm a little discouraged as I can't find new fixtures to hand the front window shield.

I'll have to make new holes to put some clamps that are more modern...

I got everything I needed to do that but it doesn't work. The shield is too high compared to the trailer so the clamp can't reach down. I'm thinking about using the old fixtures that I would paint, at least for the top part that hangs the shield.

Also, on my test drive, I realized that seeing through both windows allowed me to see behind me which is much less dangerous. I read somewhere here that someone has used the old plexiglass windows to make a shield for the front windows. Can anyone give me tips about that?

Thanks!
