Thanks BIMMER People! Anyway I need to fix my AC in an 89 735i. I just purchased a used AC compressor from a friend and I was wondering if anyone knows where I can buy a kit (fitting, tubes ect..) Also I'm amazed that my car holds 4.5lbs of freon?!!! Sorta spendy at $67 a pound. Anyway any help would be greatly appreciated. David
