Where to find accurate Frame Drawings

[JimGolden]

Hi Everyone,

I've got a '77 31 footer with the sags. I'm thinking that instead of trying to patch up the old frame, to instead fabricate a brand new frame for it. I'd like to build the new one ahead of time, so that basically once I lift the shell, I can roll out the old and roll in the new.

Where could I get an accurate drawing of the original frame? Is that something I could get from Airstream? I'd like a top view and a side view, both with some dimensions.

I've got the service manual, and it shows a couple drawings, but nothing accurate enough to build from.

Any guidance would be appreciated.

Thanks,

Jim
