80's Airstream looking for one with 48" window

[fordguy57]

question - we have a customer that has a 32ft Airstream - neighbor had concrete work done and the concrete truck backed into the side of our customers Airstream damaging the kitchen window and side wall between the window and door. We are trying to find a mid to late 80's vintage Airstream that may have a 48" widow either street side or curb side. If we can find one we are going to need a vin# to try to find a part number for the window we need. Any suggestions?
