Looking for replacement wheel assembly for Fleetwood mirrored closet door installed by California Closets in 1989

Hello, I hope you can help find replacement parts for broken wheels and wheel assemblies for Fleetwood mirrored sliding closet doors. They were installed by California Closets in 1989 and that company does not use Fleetwood closet doors any longer. I've uploaded photos with measurements.

Thank you for any info and help.
