Please only order parts if you are sure as we do not take returns on regulator parts or life support. If you have question on fit, please ask prior to order and we will try to make best answer. However realize that we have seen many-many examples of vintage regulators where parts have been mis-identified and mistakenly put into service. Just because a regulator has a part inside, does not meant that it was factory specific.
