I had a 1970 340 duster with ac and manual steering and it did not have that. why would we need it? run a shorter belt and adjust it. first thing I did was junk the ac. worth about $20
With AC you have a pair of matched belts, running the rear 2 grooves of the crank pulley, the AC compressor and the double groove pulley on the alternator. The short front belt goes around the crank pulley, the water pump pulley, and the power steering pulley which has the adjustment. Without the PS pulley, you have no way of adjusting the water pump pulley. In my old Goodyear belt application book it lists needing a 13371 belt. I cringe every time I see a nice old Mopar that has factory AC and has all the underhood stuff missing. I like to drive my 67 Dart with the R12 system intact. Most often when somebody rides with me they ask me to turn it down! Like (Damn it's cold in here!). Just my thought.
