Your part looks like the 23-016 closet roller. Compare and see what you think.

Thank you so much. Been looking for several months. So one more question do you know if 23-016 is for the top only and the other 23-234 is for the bottom only.

Correct, that is how they should go onto the door. The 23-016 is for the top, while the 23-234 guide is for the bottom. Let me know if you have any further questions.
