Here's a longshot. I'm trying to find a second set of these tweeter mounts. They are flush mounted, and fit my tweeters better than the mounts that came with em. They are in the Focal ISN 100 (4" component set). It has a ~41.65mm ID / 1.64" ID. They may also come with grill covers. Don't need the speakers, just the mounts. Would use the grills if you got em. These came with an angled mount and a flush mount, so maybe you used the other ones, and don't need these, (If by chance that SOMEHOW happened, I do have the angled mounts I would gladly trade and pay for shipping on both).
