Hello,
We have recommended one of the tracks related on this page to past customers with similar Stanely bifold door tracks in the past, depending on the length needed for your application. Keep in mind that only the low-profile versions of these tracks are still available since the 1" high version was discontinued.
If your closet uses the 1" version, you would most likely need to shim out the top track to compensate for the difference, as well as adjust the pivot pins that anchor the doors to the tracks. You can use a piece of wood, for example, to bring it down the remaining amount. Take a look and see if one of these options could work for your repair. Thank you!
