I have a 70 Dodge Challenger with a 383. My question is how do you check the proper amount of oil in the compressure. Next question is: The car had been setting for a long time, what else should I do to the air conditioner before I take it to the shop for the freon. I do have to replace the condincer as the top tube was broke. Any help would be welcome. Thanks Plum_Crazy
