Very old aluminum sliding glass door

I'm sorry to say that I don't recognize the roller assembly from these photos. It's too damaged to ID.

Do you have an undamaged version we can review? If so, I need to see it fully removed from the door without obstruction. Please note that all dimensions must also be written out in your response; a photo of a tape measure will not be sufficient for our purposes.

In the meantime, if you can reuse the housing and just replace the wheel, then I advise looking at our selection of replacement wheels and axles here.
