On the Airstream web site there’s an owner’s section, with a link to product manuals. Parts books for most years are available. You don’t need a VIN. Look up the part number and order through a dealer. I always default to Out of Doors Mart (
www.odmrv.com), and if they don’t have it, then I try Woodland Airstream (
www.woodlandairstreamparts.com).
The page with the correct part number for your trailer is attached. Find that window on line 17. Order the part. You’ll be good to go.
When the window arrives, go to YouTube to find the video of how to install it. The link is
