Ali-Express?

[wurm]

Thanks for the offer, space-time, but yes it has to be pretty strong.

Good to know about Ali-Express, Robert. I still may give them a try if only to test them out.

However Cary seems to have opened my eyes to the easiest solution. But rather than cut to size, I ended up simply bending a corner bracket enough to accomplish what I think I need to do. I guess I'll find out this weekend when I try to use it

Thanks again to everyone for your ideas.
