I assume you are looking at a VR not VS series blower and plan to install on a passenger car, not T-Bird. Any original S/C part is hard to find. There are also two stamped support brackets, I don't think anyone repops these, but they could be fabbed. Air cleaner assy, hoses, pulleys, intake manifold, and control rod were/are available repop or aftermarket. The reference fuel pump, one could use an electric with a regulator. Pressurized carburetor could be built using a standard version.
I'd be concerned about the condition of the blower. If replacement parts are available for a VR, I'd like to know where.
I'm certain John F. could add to this thread too.
