Help with 1964 Barracuda in dash speaker parts.

Those two slotted holes you see in the photo use a stud with a retainer clip. That holds the speaker frame. Then the speaker is held to that with some screws. I got a replacement upgraded speaker from a place in Blaine MN......I'm trying to remember the name of the place. If you can't google them, let me know and I'll see if I can come up with their name. I can get you a photo of mine in a '66 if that helps you any.
