Hi from sunny Atlanta, The dual air junctions for 1966 are: -- the small diameter hose connects to a "T" junction in the A/C line on the RH wheel well next to the #8 spark plug. -- The larger diameter hose connects at the A/C muffler canister, behind the battery. A special 2-outlet muffler is used with dual air. However, if your car has only a single outlet muffler, the two hoses could come together in a fabricated "T" junction connection just before the muffler, with a resulting single connection continuting into the muffler itself.
