The slider wheels still work but the retainer slots are worn.

What can be done to fix the retainer for this round corner shower door?

The problem is that the specific part shown in the photo attaches the slider to the door is cracked.

Hello, thank you for posting,

Please start by reviewing the 10-064 shower door pivot to see how it compares to your original. Unfortunately the roller assembly shown is no longer available and we are not able to provide an alternative option. I apologize for the inconvenience. Please review and let me know if you have any additional questions.
