"Blink mount" to threaded camera mount adapter?

I purchased some 3rd party mounts some time ago, and they work fine. They have a standard 1/4" threaded camera mount (like a tripod mount), and came with little plastic adapters that fit the “snap fit” adapter on the back of the Blink camera unit on one side, and the threaded camera mount on the other side. I had a couple extra mounts left over from the last set of mounts that I ordered.

Flash forward to today, and I have a new camera I want to mount. I found the box with the extra mounts, but the little adapter pieces are missing. I’ve searched Amazon for just the adapters, with no luck. Has anyone seen these adapters for sale? I’d rather not order a whole extra set of camera mounts just to get the adapters.
