Slider guide for bottom of mirrored bifold closet door

Question

The plastic guide that fits in the rail, that the door peg sticks into, has broken. I can't find where to get a replacement. I'm not sure the age of the door or the manufacturer. The label is partly covered (see photo).
Do you know if the part is still available anywhere?
Thanks.

We suggest replacing the top and bottom tracks with either our 21-450, 21-452 or 21-455, depending on the length you need. They come with the 21-175 pivot bracket and 21-174 roll guide. You will also need the 21-286 snugger to keep doors closed. The new tracks work with the 23-115 and 23-116 pins. Thank you!
