Ted, I wish you good luck. But if you get into it and find a nightmare (rotten frame or floor, for example), you can always part it out and help other people keep their Airstreams on the road. Besides, you'd make a profit over your $150 investment!
For example, I'd sure like that nice undented curved roof panel over the "AM" of "AIRSTREAM" in the picture! And there's another guy on this board trying to find a set of window frames (not necessarily the glass) for a '67 Caravel
-- I'm thinking some of your Ambassador's frames would suit nicely. There are many other vultures, um, I mean "interested parties" circling as well!
