4x10 front speaker bracket

Do you have a speaker to put in? When I saw the pic of this speaker with the tabs sticking out the ends, I thought it would go right on the studs, but no such luck. Those end tabs are kind of whimpy anyway. It took a good bit of detailed cutting to get that thing fit right without removing too much (3" cutoff ). The trickiest part was leaving enough metal for the screws to grab. It would be a lot easier to buy the bracket for the 2 small speakers...

I'm not sure when they used it, but they did make a 2 piece speaker/bracket at some point. don't know if that would be easy to modify for a new speaker. Every one I ever saw the mount frame is one piece with the speaker.
