I need the fitting that threads into the rear of the Carter AFB carburetor as used on the 1965 Cadillac Limo. The one that was in the carburetor, has had its threads cross threaded where the steel line threads into it. Since I wasn't the person that removed the carburetor from the engine, I have only a guess as to what that steel line hooks up to, and I believe that is the vacuum modulator. Please look at the picture below, and let me know if the steel line is the correct length, and if you might have the larger threaded fitting that I need. If this steel line is the proper length, then I can reuse it with the replacement fitting. Thanks for your assistance to getting this car back on the road.
