trying to get the air conditioner compressor off so I can get to the timing chain cover. Loosened the bolts in front and compressor would not move (first picture). Second picture is of a 5/8" nut in the back of the compressor (wrench attached to show location). I'm going to try to remove the two 5/8" nuts to see if the compressor moves. Has anyone removed the compressor on a 1975 New Yorker with a 440 (7.2L) engine? Paul
