Vintage 1958 Arcadia sliding glass door

I recently bought a mid-century modern house and it has original Arcadia dual aluminum sliding glass doors that are huge and in need of rollers and weather stripping. The prior home owner kept the original receipt for the door which has the door as Arcadia ALC-1 #4522. The dimension is 15' 9" x 6' 10".

Any guidance on how to obtain parts is greatly appreciated.
