I have an 87 V30. originally a 350 but now a 454. While working on it, I leaned across the engine bay, and subsequently put a crack in one of my AC lines. Now of course I have no refrigerant left and no AC. I'm trying to look for new lines, but can't quite find what I think looks like an exact replacement. Also, how can I tell if its been converted to r134a? I am about to google this and will probably find the answer, but figured I'd include the question. What else should I replace since I have to service it now anyways. How can I tell if the compressor has a lot of life left in it? Is there even a way? Here are some pictures of what the setup under the hood looks like.
