The tanks for a 21 foot Airstream, are no longer available for the 1969 or 1970 trailers from Airstream.
However, they are available after market.
A word to the wise though, there is a big difference in that from between those 2 years.
Best you have the trailer serial number handy when you decide to place an order.
Also, that tank fits above the floor.
