Bypass door rollers

Hello there! Thank you for reaching out to us. It's hard to say from this photo alone. Would it be possible for us to see a photo of this part installed? It'd also be a great help if you could write out the wheel diameter and offset. 

We carry a similar roller bracket, the 23-178, but with a solid wheel and it isn't concave like you need. Your best bet might be to replace the track and wheels to keep the doors. With that said, have a look at the kits we've related for you on this page. Review the specifications and see what you think.
