iLoad Blanked Rear Windows

Hey Guys,

So I broke the rear windows on my 2009 Hyundai iLoad (woo)

I was going to replace them but thought it would be great to not have windows there, more secuity for the van and sometimes i go camping with it and am always paranoid about people looking in. Has anyone managed to find some kind of metal sheet cover for their rear windows on an iLoad? I have a reversing camera but i can't find anything that isn't a window anywhere.
