Replacement mirror and top roller
Hello, thank you for posting,
Unfortunately we do not carry mirror replacements. I apologize for the inconvenience.
For the top roller, we recommend reviewing the style and dimensions of thee 23-222C roller assembly to see how it compares to your original. Let us know what you think and if you have any additional questions.
What you want to do is take the doors out of the frame and place them on a stable surface. To remove the rollers, you'll have to take a pair of needle nose pliers and firmly--but gently--work them out. These are hooked in, you see, and are generally in there pretty firmly. Then you just have to pop that hook out as best you can.
Unfortunately we cannot advice on the mirror removal.
Please let us know if you have any additional questions.
