Hello Everyone, I am trying to come up with the Whittek clamp sizes for the following GM part # 9423577, 9423575, 9411656, 9423581 these were used on the AIR hoses from the pump, value and by-pass? Also what quarter clamps would be typical on a March 16,1967 build date? Thanks for any help, Gary

3rd and 4th quarter 1966 would be most appropriate.
