    I had a 68 Mustang with an 'air reactor system' that was pulled off my car
    when I was in high school. The dealer actually 'bent over' and crimped the
    air tubes. Eventually they leaked and made a racket.

    Another dealer almost choked when I asked how to plug the holes telling
    me 'that's illegal!'. Heck, I just wanted to stop a leak.

    Eventually I pulled one of the 'pieces' off the manifold and got a plug from
    a plumbing supply store that fit the size and threads and screwed them in.
    Then when I had the manifold off I used a drill with a grinding ball to
    grind off what was protruding into the exhaust.

    If you go looking for something to plug the hole, DON'T let on what it's
    for. Or if you do, say it's for a motor that was pulled from a car and
    now runs a generator or something else.
