Looking for replacement wheel or pulley for sliding mirror door

Dear Swisco,

we have an old "place-built" sliding mirror door where the wheel has broken of its pulley. We have looked left and right for a fix and finally stumbled upon your site. My guess is that 23-028 is fairly close to what we have. Do you think it would work or do you have a better suggestion?

The pulley itself still works, but we are open to both replace the entire pulley or try fitting it with a replacement wheel, whatever you think is easiest.

Measurements:
Height of pulley ~3.1"
Depth of pulley ~0.5" (i.e., how much it builds on the back of door)
Wheel diameter ~1.6"
Wheel width ~0.5"
(width of pulley likely doesn't matter for our door type but is about 2.5")

Please, also see attached photos of the broken pulley, the floor rails and one of the complete pulleys.

Wheel is concave.

Thanks in advance!

Best regards,
Tomas
