I think I purchased the wrong closet door roller

A quick learner from San Francisco says:
I'm trying to replace the wheel casings on two bottom mounted slide track closet doors. The doors are no longer sliding smoothly, and I cannot determine if the bearings are bad or the wheels are just too small for the weight of the door, or both. I ordered 4 replacement wheels, item #23-043. The replacement casing height and length seemed to be a good fit, but the replacement part has a flared side which expands the width too great for the opening (9/16"). Any suggestions would be appreciated. I cannot locate any part names or numbers on the doors.

Thank you for your patience in this matter. Unfortunately, we have determined that your roller is discontinued and no longer available. At this time, we do not have a possible substitute for it. I am sorry we cannot be of more help.
A professional from California says:
If the only problem is the width of the flare, you can flatten it with pliers. The rivet may still be too wide. Your other option would be a simple wheel. 81-228 or 81-236. Your roller housings don't appear damaged. The axle should tap out with a punch and hammer.
