Mirrored closet door bottom track
What's the distance between the rails on your track? That's more important than the overall track width itself, and should be the main factor in whether these replacements can work.
Most of our concave tracks have a rail distance of about 1-11/16". Your rails are indeed wider apart it seems. Unfortunately so many different versions of these tracks were made over the years, there is always a risk of this--and not being able to find something with that distance. I am afraid you may not be able to use a new track without repositioning the doors; a pro in your area might be best to do this. I apologize for the inconvenience, and good luck with the repair.
