Quick run down on Thermactor smog pump pulleys... The 1967 system, which is only for Cougars originally sold new in California. Look on your door data plate tag, DSO should be either 52 or 53. 1967 is also unique in that they used 4 mounting bolts to the air pump. 1968 through 1970 used a 3 bolt pulley. We won't always have the full range of pulleys in stock for all applications. Fortunately they pretty much all interchange with like years and bolt patterns, even between engines.
