Car looks awesome! That body/paint guy has some serious talent! My car was also originally F3 per fender tag but its been F8 since around 1980...but that beautiful color on your car has me thinking...
Just FYI in case you are interested in some AC pulley trivia. Mine car originally had factory AC. The under hood parts been in dry storage since the early '80s (on my list to get those back on the car). A factory '69 340, with AC, but no power steering, as my car originally was, there are two idler pulleys. One is smooth and the other is V'ed. Both pulleys are between the compressor and the crank pulley. One pulley is used to adjust the belt tension the other is stationary. If interested to see how they look I can dig mine out and post up the pics; not for sale but for reference.
