I just replaced all the AC lines in my old 350Z. Its an easy job to do yourself. Just order the part that you need online and reinstall. Just don't use an oil on the o-rings and tighten back to factory specs. I saved a ton of money but just make sure you have someone vacuum out the lines and then add the gas. You could have the shop take the charge out of your line for you since I found out the gas was like $75 per pound lol. Shouldn't take you very long since the engine bay is so wide open. I had to remove all of upper turbo kit to reach mine
