Replacement wheels Part 1 of 3

Hello,

I am starting a project of trying to repair sliding patio doors. I believe the door is original from 1978. The setup is 5 doors, (from outside in) 2 identical plexiglass patio storm doors (pictures attached), 1 screen door, 2 glass doors (1 has never moved). I believe the glass doors also use the same wheels but I have not verified. They are 72 inch high doors (3 feet wide) total 6 feet long track. 

I purchased 1/4 inch 48" replacement track that seems to fit but I have not tried sliding door over it yet (in picture). I will cut to size if I can locate wheels. 

I see you also sell weather stripping and track covers so I am hoping if I can find replacement for these old wheels I might be able to order all parts I need to make life easier. I currently have the outer most door taken apart with the wheels out. 

My biggest concern beyond finding the correct wheel is the upper screw as you can see the in the frame_removed pictures. You can see the where it was threaded, this was removed via vice grips so I am not sure if a screw will go back in. It is worth giving this a try before I replace the whole frame and new doors if you carry the parts. Please let me know.

Thanks

Kevin

Hi Emily,

I took some more pictures with a ruler. The length is definitely larger than 1 3/4, although I am not sure that would matter if the other measurements are correct. It could be possible that the other measurements are correct and maybe my wheel is too damaged or has too much rust to be accurate. Let me know what you think.

Thanks
Kevin

Thanks Emily, I will give these a try on the first door. If these are not it I may need to do a full replacement. Do you know how often you might get replacement wheels like these?
