I saw things like that when I did an online search for a "mounting bracket" but none of them look like the one that's broken so I wasn't totally sure. I guess these would actually be lighter going by how much less bulk there is to them.
And thanks so much for such a quick reply. I really appreciate it.
I'll see if I can find a relatively local supplier of one of those, and then hope that when mine broke, nothing else died at the same time.
