Replacing sliding mirrored closet doors bottom track

Question

I don't have any markings on the parts. I have hired a contractor who is doing a remodeling project. We have not seen any railings that might fit these doors. The doors have concave runners (IMG_0481). I'm wondering if you have a 72" track that these wheels will work on? If these rollers don't work on your track, I'm wondering if we can replace the rollers? I really appreciate any ideas you might have for a solution to our dilemma. Thank you.

Thanks for posting. If you need a track for concave runners, then our 71" 23-272 immediately comes to mind. See the end profile dimensions below for reference. Note that the critical dimension here is the distance between the two tracks. While ideally you'd want the overall track width to be the same too, you can usually find room to fit a track with a slightly different overall width--it's the distance between the rails that is less negotiable. Let me know what you think.
