Did some one mention tha A/C exempted the air? My Ca 66 Monza 140 PG with A/C has no air cuz A/C takes up room in the engine compartment and the second pulley. Engine is T1227RY Serial 10537L107609. Also has positraction. I don't think the posi is part of this discusion. Kirk Johnson above 66 Monza 1962 Monza Wagon Lincoln, Ne
