You must cut the original brass outlet off the fiberglass tank.
Then, you can carefully fiberglass the flange, the white part you show in your photo, to the tank.
Make sure that you orient the flange so that the valve can easily be installed.
Other than that, there is no simple solution, since your Airstream is from the early 60's.
