    I’ve seen black and I’ve seen cad-plated. I might have both.

    In my Nov. '71 parts manual There is just one part number for the vacuum modulator listed for the ST400, THM400, Turbo400, Turbo 350, and the Super Turbine 300 with v-8 engines.
    I have a good one of these. I'll test to make sure it works (hold vacuum) tomorrow if you are interested.
    The part number is 8625976 gr. 4.205
