Markings printed on part:21-717 and 21-767.

The plastic wheels have broken and was moved off the track on the floor. These are wheels that were placed on the bottom of the mirror sliding doors (not the type that has wheels/track on the top.) i am looking to replace the part on the doors. Thank you for any help you can offer.

Take a look at our 23-070 Concave Roller. This has been used in the past to replace Cox rollers like yours. See what you think.
