Ford used steel vacuum line and a compression fitting called a "Ford Nut" at the vacuum advance canister, and at the carburetor. I can source those, but not the carb fitting.

The fitting looks like the one on the right in the pic, this is necessary to make it work. Anybody know a source for these or part number?
