Mirror door roller

The wheel on the roller assembly popped off and it cannot be put back on. The assembly has two pieces; the part that gets screwed on to the door and the part that slides onto the first piece into place. I searched everywhere on the mirror doors without finding any numbers or markings. I attached multiple pictures. Both of the unbroken roller assembly and the broken one uninstalled. Hoping for a replacement. The wheel is 1 1/2 inch in length all the way around and 5/16 in thick
