Hello. Help. I installed a original Air AC system. The new S6 style pump is shorter than the original A6 Frigidaire Pump. Anyone install Original or Vintage Air Kits in 70-72 Skylark (350)? I was told i need a 3 groove pulley. It seems like the extra groove in the pulley is further away not closer to the engine for belt alignment. I was thinking of making a bracket to bring out the AC pulley about 3/4"
