I was trying to fit some headers on my 350, but i need to take out what looks like a little bottle that has hard lines run through the A/C condenser. I figured that it held the freon. When i turned to nut loose just to find out what would leak out, i could hear a gas excaping, is it under pressure, or what? Is it ok to take this off, what will happen, or what will i need to do to save my A/C? I already have to cut up the driverside header to clear the steering shaft, i don't want to have to do them both.
