Attached find label of door. Pics of the 4 corners of the door. Do you have replacement tracks for these doors?
I can see that a spring and cotter pin is missing but have no idea if anything else is missing.
Thanks for reaching out to us. We unfortunately don't sell tracks for these doors. We do sell a variety of different Leigh brand pin assemblies, but it's far from an exhaustive list. To be honest a lot of the parts used on this door are no longer available, so they're very difficult to come by. It will be even harder to determine what you have if there are important components missing. We don't have an parts list for this door, so we really depend on using the original hardware as a reference for identification. If that hardware is missing, we can't narrow it down.
For now I've made a list on this page of all the Leigh brand pin assemblies we sell. I recommend starting with this list. We have detailed dimensions on their respective store pages that you might find helpful.
