after my swap i left my old ac compressor from my d15 attached to the lines and its just bolted down out of the way currently. i have a b series compressor and the ac bracket, i just need to know if its safe and how to go about removing the lines from my stock AC unit so i can put the new one in. thanks for any help.

 

I'm not sure about this either. I think theres a vacume you might need to use to take the refrigerent out since that stuff is really toxic.
