None are reproduced. There are a few floating around.

What year do you have? 1969-70 are different than 1971-72.

The earlier version twists into the valve cover and has a twist on steel cap with cork gasket. The later version sits in a grommet and has a push in rubber cap. Both are secured using a steel brace bolted to the intake manifold.

1971-72:
