Concave wheels

Thanks for writing in! I'm afraid we do not. May I see a photo of the existing closet roller? To get a better idea of a possible recommendation, I'll need to see the exact details of the roller.

Please let me know if you have questions.

Thanks for the additional photos. You may be better suited to replace the track. This may be an easier option than attempting to modify the door and/or the roller to be compatible with the track.

I've tagged the compatible convex track below. It comes in three different lengths.
