Speaker Bracket Replacement

When I bought my boat the left-side tower speaker bracket was missing it's "C" bracket. I've emailed Aerial to try and ID the part but I'm not even sure if it was their's to begin with. The Y bracket says Aerial so I assume so but not 100% sure. I believe that this was an addition to the boat after 2005 as Aerial didn't open until 2007.

Am I headed down the right path here? Any other options or companies I should be emailing/calling to try and find this? Easier to take the right-side one to a metal fab shop and see if they can trace/cut it?

See pictures attached.

Probably fab shop is best bet
