Old glass aluminum sliding door

I suspect the door to be around the age of the home, and the homes interior walls are made of plaster. The wheel assembly is almost, if not entirely made of aluminum (very fragile metal that broke when replacing the wheel).

I managed to forget to measure it once I had removed it and am now just trying to find someone with a similar door. The door comes apart with four corner screws (one in each corner) and the wheels are held on by the screws. There are only bottom wheels, the top track has 2 inches of room to lift the door out.
