Broken top guide sliding mirror door

Thanks for reaching out to us! I agree, our 23-038 appears to be our best bet for this.

We unfortunately don't have any instructional guides for how to replace this hardware, but the process is fairly straightforward. These just hook into the mirror door frame; there are no screws or clips that hold them in. To remove, take the doors down and place them on a flat, stable surface, ideally the floor. Then take a pair of needle nose pliers and gently work the guide housing back and forth to unhook it from the frame.

That's really all there is to it. It'll take some patience and a little elbow grease, but it will come out if you're persistent.
